IngredientsSuma is the widely used common name for a perennial, rambling ground vine whose current accepted botanical name is Hebanthe eriantha (Poir.) Pedersen. Known as suma or Brazilian ginseng, it is a species of plant in the family Amaranthaceae. The name most frequently encountered in pharmacological and ethnobotanical literature is Pfaffia paniculata (Mart.) Kuntze, which remains in wide use. Since its first botanical recording in 1826, it has been referred to by several botanical names, including Pfaffia paniculata, Hebanthe paniculata, and Gomphrena paniculata. Additional synonyms documented in patent and taxonomic literature include Gomphrena eriantha, Iresine erianthos, Iresine paniculata, Pfaffia eriantha, and Xeraea paniculata.
Pfaffia paniculata is sometimes included under the name Hebanthe eriantha — both are synonymous and refer to the same plant. Suma is a member of the Amaranthaceae family of plants, placing it in botanical relation to spinach, beet, and quinoa. The genus Pfaffia is well known in Central and South America, with over 50 species growing in the warmer tropical regions.
A closely related species, Pfaffia glomerata (Spreng.) Pedersen, is frequently studied alongside P. paniculata and is sometimes sold under the same common names, though it is a botanically distinct taxon. Research from one 2024 review in the Journal of Ethnopharmacology provides a comprehensive account of P. glomerata's botany, ethnopharmacology, and biological activities as a species in its own right.
Suma is a large, rambling, shrubby ground vine with an intricate, deep, and extensive root system. It is indigenous to the Amazon basin and other tropical parts of southern Brazil, Ecuador, Panama, Paraguay, Peru, and Venezuela. Suma is a woody, vine-like plant with large, compound leaves and clusters of small, white flowers. The roots grow deeply and extensively, forming a large taproot — this is the part used as medicine.
Suma is known under several vernacular names across its range and in international trade. Nicknamed "para tudo" in Brazil, which means "for everything," suma is a traditional herbal medicine. Referred to by the people of the rain forest as para todo, which can be translated "for all things," the herb has been used for 300 years in the Amazon for many different ailments. Additional common names in regional and commercial contexts include corango-açu and "Brazilian ginseng." Suma has been marketed as Brazilian ginseng, though it is not related to Asian ginseng or American ginseng. This name is misleading; while suma displays some similar properties to ginseng, Pfaffia paniculata is not part of the ginseng plant family — it is an amaranth.
Pfaffia root is a very important medicinal herb with a very long history of traditional use amongst the indigenous peoples of the Amazon region. Regarded as a general cure-all, it was and is used as a tonic and rejuvenating herb to treat a wide range of illnesses and restore virility to the body.
The common names for Pfaffia paniculata reflect its broad spectrum of medicinal benefits and applications in traditional Peruvian medicine — such as a sexual tonic, general health tonic, vulnerary, antibacterial, and for ulcers of the skin and digestive system. In Brazil, Pfaffia paniculata is used for anemia, arthritis, asthma, cancer, chronic fatigue syndrome, circulation problems, diabetes, hypertension, hyperglycemia, immune disorders, impotence, inflammation, leukemia, lymphatic diseases, pain, rheumatism, skin problems, stress, tremors, tumors, and ulcers, and as an aphrodisiac, appetite stimulant, and antioxidant.
A research study investigating the literature of 24 books in Brazil, looking for indications of adaptogenic plants from the region that are listed in more than four books, found that pfaffia was one of the most utilized tonic botanicals in Brazil, but was listed in fewer than four books. This finding places some qualification on claims about the depth and breadth of its documented traditional use.
Importantly, although suma is claimed as an ancient Brazilian folk remedy, no confirmation of that statement is found in the modern literature on medicinal plants. Although suma is claimed as an ancient Brazilian folk remedy, no confirmation of that statement is found in the modern literature on medicinal plants. Scholars and clinicians evaluating the evidence have noted the gap between popular claims and what is verifiable in ethnobotanical records.
In Brazilian traditional herbal medicine, a decoction is prepared by boiling 10 g of suma root in one litre of water; generally two cups of this decoction are consumed every day. Herbal medicine practitioners and herbalists in Brazil also use the root powder in capsules, as the decoction has a bitter taste. Suma root has traditionally been prepared by crushing the roots into a fine powder, which can then be ingested with other foods or on its own, or made into tea.
The root of P. paniculata contains a chemically complex array of bioactive molecules. The most pharmacologically studied classes include ecdysteroids, nortriterpene saponins (pfaffosides), and phytosterols.
The main plant chemicals of suma are: allantoin, β-ecdysterone, β-sitosterol, daucosterol, germanium, iron, magnesium, nortriterpenoids, pantothenic acid, pfaffic acids, pfaffosides A, B, C, D, E, and F, polypodine B, saponins, silica, stigmasterol, stigmasterol-3-O-β-D-glucoside, and vitamins A, B1, B2, E, and K, as well as zinc.
Chemical analysis confirms that P. paniculata roots contain two types of phytosteroids, beta-sitosterol and stigmasterol, in addition to other compounds such as pfaffic acid, allantoin, saponins, beta-sitosteryl-beta-D-glucoside, and stigmasteryl-beta-D-glucoside. The plant has also been reported to contain 19 amino acids. Suma root contains 19 different amino acids, a large number of electrolytes, trace minerals, iron, magnesium, zinc, and vitamins A, B1, B2, E, K, and pantothenic acid.
Suma root contains several major constituents, including the nortriterpene pfaffic acid, six pfaffic acid saponins (pfaffosides A–F), pterosterone, ecdysterone, and ecdysteroid glycosides. The saponin content, in particular, is reported to be quite high in this plant (up to 11%), which has been associated with adaptogenic plants in many other cases and provides a broad spectrum of effects including anti-cholesterol, anticancer, and antimicrobial activity.
P. paniculata contains pfaffic acid, and the saponins pfaffosides A, C, D, E, and F in its composition, which showed inhibitory effects on the growth of cultured murine melanoma B-16 cells (Takemoto et al., 1983; Nakai et al., 1984; Nishimoto et al., 1984). These same saponins as well as pfaffic acid were the subject of several Japanese patents in the 1980s for their anti-tumor effects.
Pfaffia also includes β-ecdysterone (0.63%) and ecdysteroid glycosides, which have been attributed to many of its benefits, including adaptogen-like effects, hormone modulatory effects, and athletic performance, among others. From the crude drug "Brazil ginseng," the roots of Pfaffia iresinoides (a related species), a large amount of ecdysterone has been isolated together with polypodine B and pterosterone.
20-Hydroxyecdysone is a phytoecdysteroid produced by and extracted from various plants, including Cyanotis vaga, Ajuga turkestanica, and Rhaponticum carthamoides; it is thought to be a plant defense against herbivory that disrupts the reproduction of insect pests. Although mammals (including humans) lack the ecdysone receptor, 20-hydroxyecdysone affects mammalian biological systems.
Two plant hormones, sitosterol and stigmasterol, occur naturally in suma. These two plant hormones are phytoestrogens — plant compounds that mimic some of the properties of estrogen. These phytosterols are considered to be partly responsible for the hormonal effects observed in animal studies.
Constituents include pfaffosides A, B, C, D, E, and F; sitosterol; stigmasterol; allantoin; and germanium. Allantoin is a nitrogen-containing compound found in many plants, associated with cell-proliferating activity and wound healing.
In modern herbal medicine the root is considered to be an adaptogen and a tonic, able to increase the body's resistance to adverse influences by a wide range of physical, chemical, and biochemical factors and having a normalizing or restorative effect on the body as a whole. The classification of suma as a true adaptogen remains debated. Suma has been marketed as Brazilian ginseng, though it is not an adaptogen (a substance that invigorates or strengthens the system) and is not related to Asian ginseng or American ginseng — a characterization offered by PeaceHealth's evidence-based health library. Other sources and herbal databases do classify it as an adaptogen based on its phytochemical profile and in vivo studies.
In spite of more than 40 years of research, the mechanism of action of these molecules on mammals and humans has not been fully elucidated, as only diverging reports are available. Several data favour an action on membranes through a GPCR receptor, whereas others suggest the involvement of a nuclear receptor, the estrogen receptor ERβ. In mammals, 20-hydroxyecdysone is hypothesized to bind to the estrogen receptor beta (ERβ) protein. There is in fact no direct evidence for the binding of 20-hydroxyecdysone to nuclear estrogen (or androgen) receptors.
Intestinal anti-inflammatory activity of P. paniculata was related to modulation of Mapks and mucin gene expression, as well as mucus secretion in intestinal inflammation. Research using TNBS-induced colitis in rats demonstrated that MPO activity was reduced, GSH levels were maintained, and the levels of pro-inflammatory cytokines and CRP were decreased. The protective effect of P. paniculata was related to reduced oxidative stress and CRP colonic levels.
The alcoholic extract of Pfaffia paniculata dried roots was studied for analgesic anti-inflammatory activity in the rat paw oedema test, writhing test, hot plate test, and increased vascular permeability. Pfaffia paniculata inhibited the carrageenan-induced rat paw oedema and increased vascular permeability and showed analgesic activity on inflammatory pain but not on noninflammatory pain.
Male mice receiving different doses (100, 250, or 500 mg/kg) of the methanolic extract of P. paniculata by gavage once daily for 10 days showed that macrophage activity was evaluated through the phagocytosis index, spreading index, and production of peroxide oxygen and nitric oxide. The methanolic extract raised significantly the spreading index of mice from the 500 mg/kg group in comparison with controls. This increase of spreading index possibly induced the higher phagocytic activity observed. Increased macrophage activity may be one of the effects contributing to inhibition of the Ehrlich ascitic tumor growth in mice.
Levels of the sex hormones estradiol-17β, progesterone, and testosterone were clearly higher for mice that drank P. paniculata root-enriched water than for mice that drank plain water. These effects are attributed primarily to the phytosterol content (beta-sitosterol and stigmasterol) and the ecdysteroid compounds in the root.
The most extensively studied area related to suma's key compound, β-ecdysterone (20-hydroxyecdysone), concerns its potential anabolic and ergogenic effects. This research does not test whole suma extracts in clinical trials but rather the isolated ecdysteroid constituent.
A 2006 study concluded that the use of 30 mg per day of 20-hydroxyecdysone administered orally did not significantly affect anabolic or catabolic responses to resistance training, body composition, or training adaptations. However, a 2019 study found significantly higher increases in muscle mass and one-repetition bench press performance in participants dosed with ecdysterone. This study, funded by the World Anti-Doping Agency, demonstrated a significant dose-responsive anabolic effect.
The 2019 study (Isenmann et al., Archives of Toxicology) is the most cited human clinical trial involving ecdysterone. The study noted that the anabolic effect of ecdysterone, a naturally occurring steroid hormone claimed to enhance physical performance, is mediated by estrogen receptor (ER) binding. In comparison with prohibited anabolic agents such as metandienone, ecdysterone revealed to be even more effective in a recent study performed in rats. However, scientific studies in humans were described as very rarely accessible at the time.
Phytosteroids like 20-hydroxyecdysone and diosgenin have shown promising anabolic and performance-enhancing effects in in vitro, animal, and human studies. Evidence as of 2025 remains preliminary and is largely confined to small human trials and in vitro / animal models. No large-scale randomized controlled trials using whole suma extract have confirmed ergogenic benefits in humans.
This is one of the few areas where suma (Pfaffia paniculata extract) has been examined both in a controlled human context and in a published clinical trial. A study published in Clinical Hemorheology and Microcirculation (Mozar et al., 2015/2016) tested the effects of Pfaffia paniculata extract on red blood cell (RBC) rheological properties of patients with sickle cell disease (SCD) and healthy individuals. Blood from 7 SCD and 4 healthy individuals was collected; washed RBCs were incubated with concentrations of 0.0, 0.2, or 0.5 mg/mL of PP extract for 5 hours at 37°C. While RBC deformability was not improved by PP extract in healthy controls, an improvement was noted in patients with SCD between the 0.0 and 0.5 mg/mL conditions.
This finding aligns with earlier patent-reported data. In a double-blind placebo human study, 15 patients taking suma root for three months (1,000 mg three times daily) increased hemoglobin levels, inhibited red blood cell sickling, and generally improved their physical condition. The small sample sizes in these studies and the ex-vivo nature of the 2015 study limit the strength of these conclusions. The evidence is preliminary but is among the most directly human-relevant data available for suma.
Preclinical evidence supports anti-inflammatory activity of P. paniculata extracts. Pfaffia paniculata is an adaptogenic medicinal plant used in Brazilian folk medicine as an "anti-stress" agent; researchers hypothesised that P. paniculata enhances the response of animals subjected to colonic inflammation. The aim was to investigate the intestinal anti-inflammatory activity of P. paniculata in rats before or after induction of intestinal inflammation using trinitrobenzenesulfonic acid (TNBS).
To evaluate intestinal anti-inflammatory effects of P. paniculata on the mRNA abundance of Hsp70, Heparanase, Mapk1, Mapk3, Mapk6, Mapk9, Muc1, Muc2, Muc3, Muc4, and NF-κB as well as mucin content in colonic samples, intestinal inflammation was induced by TNBS and rats were divided into groups that received vehicle or 25, 50, 100, or 200 mg/kg of P. paniculata extract, administered orally, started 2 hours after inflammation induction and continued daily for 7 days. Treatment with the P. paniculata extract was able to control inflammatory markers, and the microscopic evaluation demonstrated a significantly reduced structural damage.
All anti-inflammatory evidence remains at the animal (rodent) stage. No clinical trials in humans with inflammatory bowel disease or other inflammatory conditions using P. paniculata have been published as of mid-2025.
While Pfaffia paniculata is commonly called the "cure-everything," its scientifically proven benefits are limited to anti-inflammatory and antioxidant actions. Nevertheless, a body of in vitro and animal research explores potential antitumor mechanisms.
Test tube studies do indicate possible anti-tumor activity of suma constituents called pfaffosides. Mice with thymic lymphoma treated with powdered roots of P. paniculata showed reduction in tumor burden (Watanabe et al., 2000). Also, this plant extract was studied for growth inhibitory effects on transplantable Ehrlich tumor cells in ascitic form (Matsuzaki et al., 2003, 2006).
In addition to the pfaffic acids having anticancerous activity, research in Japan (in 2000) reported that natural suma root had anti-cancerous activity as well. In this in vivo study, an oral administration of powdered suma root at a dosage of 750 mg/kg was reported to inhibit the proliferation of lymphoma and leukemia in mice and delay mortality. This antiproliferative effect slowed the growth of cancer cells — it did not eradicate them. The researchers postulated that the inhibitory effect might be due to enhancement of the nonspecific and/or cellular immune systems.
A smaller total area of neovascularization in the mouse cornea was observed in animals treated with 1,000 mg/kg of the methanolic extract of P. paniculata, indicating an antiangiogenic effect of this extract. The mechanisms of this antiangiogenic activity should be further investigated.
One patent suggested evidence to support 100 mg/kg of pfaffia saponins orally in rats as active against gastric cancer. Other patents showed evidence that pfaffic acids provided strong in vitro activity against melanoma, liver carcinoma, and lung carcinoma cells at a dose of 4–6 mcg pfaffic acids — which equates to approximately 400–600 g of natural pfaffia root. These doses are quite high, and therefore in these cases an extract will need to be standardized and used, or else these chemicals will need to be synthesized.
Evidence characterization: All anticancer evidence for suma is preclinical (in vitro or animal model). No human clinical trials investigating suma or its constituents as oncological interventions have been published.
Animal studies suggest that P. paniculata root can alter endogenous hormone levels. One published study undertook chemical analysis of components of Pfaffia paniculata roots and conducted an animal experiment in which mice had ad libitum access to water enriched with powdered P. paniculata root for 30 days, monitoring changes in plasma concentrations of estradiol-17β and progesterone in female mice and testosterone in male mice. The results showed that levels of the sex hormones estradiol-17β, progesterone, and testosterone were clearly higher for mice that drank P. paniculata root-enriched water than for mice that drank plain water.
The stimulant effects on male sexual behavior have also been examined. A study published in Psychopharmacology (Arletti et al., 1999) examined the stimulating property of Turnera diffusa and Pfaffia paniculata extracts on the sexual behavior of male rats. All such evidence remains animal-based; no controlled human trials on suma and hormonal or sexual outcomes have been reported.
Laboratory studies have reported an increase in immunity, as shown by increased macrophage activity. Laboratory studies have found that extracts of P. paniculata can increase levels of sex hormones, like estrogen (estradiol), progesterone, and testosterone. The macrophage activation studies, conducted in mouse models at doses of 100–500 mg/kg, demonstrated dose-dependent increases in phagocytic spreading index, suggesting immunostimulant potential. These findings have not been validated in human clinical trials.
While Pfaffia paniculata's scientifically proven benefits are limited to anti-inflammatory and antioxidant actions, a 2024 study (published in PMC) aimed to determine the spectrum of antimicrobial activity of Pfaffia paniculata and assess its cytotoxicity. A potential antimicrobial action against Staphylococcus aureus was observed at concentrations of 250 and 500 mg/mL, with inhibition halo formation of 11 and 21 mm, respectively. Additional recent work has examined the antimicrobial potential of P. paniculata extracts against periodontal pathogens including Porphyromonas gingivalis.
Preclinical research on 20-hydroxyecdysone (the principal ecdysteroid in suma) has explored cardiometabolic applications. One animal study concluded that 20E treatment can alleviate cardiometabolic disorder caused by a high-fat–high-fructose diet and female sex hormone deprivation. In particular, 20E helps improve whole body insulin sensitivity in the model used, with mechanisms potentially mediated by the activation of AMPK and FGF21. The study suggests that 20E could be an alternative therapeutic option for the prevention and alleviation of cardiometabolic syndrome. This evidence is exclusively animal-based and cannot be directly extrapolated to humans or to whole suma root preparations.
The compound 20-hydroxyecdysone, found in suma, has entered early-phase clinical investigation as a pharmaceutical agent (branded as "BIO101") for sarcopenia and muscular conditions, distinct from whole-root supplementation. A Phase 1 study for safety and pharmacokinetics of BIO101 (20-hydroxyecdysone) in healthy young and older adults was published in the Journal of Cachexia, Sarcopenia and Muscle in 2023 (Dioh et al.). A Phase 2b double-blind randomised interventional trial (Fielding et al., 2025) in sarcopenic seniors at risk of mobility disability has also been published. These trials investigate a purified form of 20-hydroxyecdysone as a pharmaceutical drug candidate and should not be conflated with suma root supplementation studies, which do not exist at this clinical level.
In its simplest form, suma root can be purchased as a powder that can be mixed with a beverage of choice. Other available forms include powdered capsules, teas, and liquid extracts. More recently, techniques have been developed to extract suma's nutrients into alcohol or into concentrated powder capsules. These alcohol-based tinctures and pills can be consumed as nutritional supplements.
Supplementing with suma in its raw powder form is described as the best way to acquire the fullest dose of the many vitamins, minerals, electrolytes, and amino acids that its roots contain. In contrast, using chemical extracts — such as alcohol-based tinctures — is better suited for obtaining the most potent dose of ecdysteroids, pfaffosides, and saponins.
Most of suma's constituents are water-soluble, which means the plant may also be used as a tea or in capsules.
The following dosages appear in published sources and should not be interpreted as clinical recommendations:
Not enough research confirms the effectiveness or safety of these dosage recommendations.
Based on the pharmacological literature, the following body systems and health areas are the focus of suma-related research or traditional use:
Suma has not been associated with any serious adverse reactions. However, comprehensive safety studies have not been undertaken. As no adverse reactions were seen in mice within 30 days of oral intake, consumption of P. paniculata for long periods of time appears safe based on animal data. A toxicological study employing 250, 500, or 1,000 mg/kg/day of the methanolic extract by gavage in BALB/c mice found that animals did not lose weight during the treatment nor presented histopathological alterations.
A patient developed occupational asthma after exposure to Pfaffia paniculata root powder used to manufacture Brazilian ginseng capsules. However, the ginseng extract did not have the same effect on subjects who had not been previously exposed to the ginseng dust. This case, reported in the Journal of Allergy and Clinical Immunology (Subiza et al., 1991), represents a documented sensitization hazard from inhalation of raw root powder, relevant primarily to workers in manufacturing settings rather than consumers taking encapsulated or tea forms.
Ingestion of large amounts of plant saponins in general (naturally occurring chemicals in suma) has been shown to sometimes cause mild gastric disturbances including nausea and stomach cramping. Dosage reduction may alleviate these effects.
Decreased sperm viability has been reported in an animal study in which Brazilian ginseng was administered to male mice for 42 days. At the end of this trial, the researchers discovered that the mice had decreased daily sperm production and fewer resistant spermatids in the testis. This finding, from rodent studies, raises a potential reproductive concern that has not been evaluated in human subjects.
Safety of the use of suma by young children, pregnant or nursing women, and those with severe liver or kidney disease has not been established. Despite having been used as a traditional herbal remedy, there are no recent studies on the root's possible side effects or overall safety profile.
No drug interactions have been formally reported in the published literature for suma. However, given the hormone-modulating effects demonstrated in animal studies (elevated estradiol, progesterone, and testosterone), theoretical interactions with hormonal therapies, hormone-sensitive conditions, and medications affecting the HPA axis cannot be excluded, though these have not been formally characterized in human studies.
One study showed anti-inflammatory activity both in vivo at 100 mg/kg and in vitro at concentrations of 50 and 100 μg/mL. A pro-inflammatory effect was verified at the dose of 200 mg/kg by pleurisy assay, and at 200 μg/mL by the in vitro chemotaxis test. This dose-dependent inversion of effect is a notable pharmacological finding suggesting that higher doses of suma extract may paradoxically promote rather than inhibit inflammation in some experimental contexts.
In light of the lack of known traditional use confirmed in the modern ethnobotanical literature, and of modern research confirming health benefits, the evidence base for clinical use of suma is currently insufficient to recommend it for any specific condition. What little research has been done focuses on the plant's anti-tumor, anti-inflammatory, and aphrodisiac effects and has been completed only in test tubes or with animals.
The principal research gaps include: (1) the complete absence of rigorous, randomized controlled trials testing whole suma root extract in humans for any indication; (2) the conflation in the broader literature between research on isolated 20-hydroxyecdysone (often from other plant sources) and whole-root suma supplementation; (3) the lack of standardized extracts for clinical use and the variability of phytochemical content between preparations; (4) the absence of formal pharmacokinetic data in humans for suma root specifically; and (5) the absence of safety surveillance data in women who are pregnant or breastfeeding.
The most clinically relevant emerging area is the pharmaceutical development of purified 20-hydroxyecdysone for sarcopenia and muscular conditions, which if successful could illuminate bioavailability, dosing, and safety parameters applicable to suma as a source plant. However, this pharmaceutical research (BIO101) is distinct from conventional suma supplementation and cannot be used to validate herbal product claims.
Health conditions that Suma may help support.
A double-blind, placebo-controlled human study (cited in a 1995 US patent) found that suma root at 1,000 mg three times daily for three months improved hemoglobin levels and inhibited red blood cell sickling in sickle cell anemia patients. A 2015 clinical hemorheology study also reported improved RBC deformability in sickle cell patients with P. paniculata extract.
Pfaffia species demonstrate antioxidant activity in multiple preclinical models. Franco et al. (2021) showed that a 20-hydroxyecdysone-enriched fraction maintained antioxidant enzyme defenses in the brain cortex and striatum of stressed mice. Phytochemical analyses confirm the presence of antioxidant-active saponins, polyphenols, and ecdysteroids.
The 20-hydroxyecdysone-enriched fraction from P. glomerata roots significantly reduced anxiety-related behaviors in mice at 30 mg/kg (Franco et al., 2021). Traditional use of suma by indigenous Brazilians as a calming tonic aligns with this finding.
Beta-ecdysone derived from Pfaffia species has been shown in animal models to attenuate cartilage damage in collagenase-induced osteoarthritis via modulation of the FOXO1/ADAMTS-4/5 signaling axis. General anti-inflammatory effects of P. paniculata in animal models also support a relationship with arthritis.
Animal studies demonstrate that Pfaffia paniculata extract exerts anti-inflammatory activity via suppression of pro-inflammatory cytokines and NF-κB pathways. Alcoholic root extract inhibited carrageenan-induced paw edema and reduced vascular permeability in rats. Active constituents including saponins, pfaffic acid, and phytosterols are considered responsible for these effects.
Alcoholic P. paniculata root extract demonstrated analgesic activity specifically against inflammatory pain in rat models, including inhibition of carrageenan-induced edema and writhing test responses (Mazzanti & Braghiroli, 1994). The analgesic effect was absent for non-inflammatory pain, indicating a mechanism tied to inflammation pathways.
The same Arletti et al. (1999) rat study demonstrated that P. paniculata extract improved copulatory performance in sexually impotent rats, including metrics directly related to erectile and ejaculatory function. This is the primary published evidence for this link, supported by traditional use as a sexual restorative.
P. paniculata root consumption significantly elevated plasma estradiol-17β and progesterone in female mice after 30 days (Oshima & Gu, 2003). The plant is noted to have hormonal-like effects, and caution is recommended in estrogen-sensitive conditions. No human clinical trials confirm estrogenic effects.
Animal studies show P. paniculata and related Pfaffia species modulate testosterone and reproductive parameters in male rodents, though results are mixed. One study noted elevated testosterone; another on P. glomerata showed altered testicular microstructure with hydroalcoholic extract at higher doses. No human fertility studies exist.
Two published preclinical studies demonstrated that P. paniculata extract significantly reduced intestinal inflammation in TNBS-induced colitis in rats, reducing macroscopic injury, pro-inflammatory cytokines, and oxidative stress markers. Modulation of MAPK and mucin gene expression pathways was identified as a mechanism.
P. paniculata extract improved copulatory performance in sexually sluggish or impotent male rats in a published pharmacological study without affecting locomotor activity. The effect appears specific to sexual dysfunction rather than normal sexual function. Traditional use as an aphrodisiac is well-documented across South American herbal medicine.
P. glomerata extract supplementation improved learning and memory in aged mice over 150 days in a published pharmacological study. Anticholinesterase and antiglycation activity of P. glomerata fractions have also been reported in vitro, providing mechanistic support for cognitive effects.
A 20-hydroxyecdysone-enriched fraction from Pfaffia glomerata roots was shown to reduce stress, anxiety, and depression parameters in an acute murine model, while maintaining antioxidant defenses in the cortex and striatum. This preclinical finding supports suma's traditional use as an adaptogenic anti-stress herb.
A published mouse study (Oshima & Gu, 2003) found that 30 days of P. paniculata root powder consumption significantly elevated plasma testosterone levels in male mice compared to controls. The effect is attributed to phytosterols (beta-sitosterol, stigmasterol) and ecdysteroids. No human clinical data exist.
Suma (Pfaffia paniculata), known as 'Brazilian ginseng,' has traditional use in South America as an adaptogenic tonic for energy and endurance. Its proposed ergogenic compounds include ecdysteroids (beta-ecdysone) and pfaffosides. It is listed as a proposed ergogenic aid in the EBSCO Research Starters sports performance database.
Suma is listed in traditional Brazilian folk medicine as an antidiabetic agent. Cell studies show that ecdysteroids from Pfaffia species increased hepatic glucose utilization by 44–77% in vitro, providing biochemical rationale. It has been described as hypoglycemiant in X-ray fluorescence characterization studies. No human clinical trials confirm antidiabetic efficacy.
Suma is documented in Brazilian folk medicine as a traditional remedy for fatigue and exhaustion, classified as an adaptogen and tonic. It is listed among the traditional therapeutic indications for P. paniculata alongside stress and low immune function. Clinical evidence is absent.
Suma has a long tradition of use in South American indigenous medicine for increasing physical energy, vitality, and stamina. Known as 'para toda' (for everything), it is classified as an adaptogen believed to support the body's energy systems. One double-blind clinical study on the related species Pfaffia glomerata found no statistically significant benefit for physical performance in volunteers.
Suma has been used in South American traditional medicine as a longevity tonic and general restorative. Its antioxidant profile, adaptogenic properties, and nutrient density support broad traditional use for healthy aging. Memory-enhancing effects of P. glomerata in aged mice provide modest preclinical support.
Suma (Pfaffia paniculata), known as 'Brazilian ginseng,' is a South American adaptogen used traditionally for stress, fatigue, and vitality. It is included in integrative HPA axis support formulations and databases. Preclinical evidence suggests adaptogenic, anti-stress, and hormone-modulating properties; robust human RCTs specifically measuring HPA axis markers are lacking.
Suma is traditionally used in South American folk medicine to alleviate menopausal symptoms such as hot flashes and mood changes, supported by its documented ability to modulate estradiol and progesterone levels in animal studies. No human clinical trials have confirmed efficacy for menopausal symptoms.
Suma's ecdysteroid content, particularly beta-ecdysterone, is associated with anabolic-like effects on muscle tissue in animal and cell studies. Traditional folk use recommends suma for athletes and those with physically demanding lifestyles for recovery and strength building. No human RCTs on suma specifically for muscle recovery have been published.
Suma has extensive traditional use for increasing athletic endurance and physical stamina, and its beta-ecdysterone content earned it the nickname 'the Russian secret' for alleged use by Soviet Olympic athletes. A human placebo-controlled trial with P. glomerata found no significant performance benefit. Evidence remains traditional and mechanistic.
Suma is used in traditional South American herbal practice to relieve PMS symptoms, attributed to its phytosterol and ecdysteroid content that may modulate estrogen and progesterone levels. This use is documented but unconfirmed by human clinical trials.
Suma root has been applied topically in South American traditional medicine for wound healing and skin problems. Its content of allantoin—a compound with established cell-proliferating and wound-healing properties—and ecdysteroids that promote cellular repair provide a biochemical rationale for this use.
