Cynomorium

Cynomorium: A Comprehensive Reference

1. Identity, Taxonomy, and Natural Source

Cynomorium is a genus of parasitic perennial flowering plants in the family Cynomoriaceae. The genus consists of only one species, Cynomorium coccineum, although one of its subspecies is sometimes treated as a separate species. The two taxa most commonly referenced in the scientific literature are C. songaricum Rupr. and C. coccineum L., both placed within the family Cynomoriaceae.

From a strictly modern botanical standpoint, Cynomoriaceae is a monotypic family including one species, Cynomorium coccineum, which is divided into two subspecies: Cynomorium coccineum subsp. coccineum and C. coccineum subsp. songaricum (Rupr.) J. Léonard (1986). Several authorities continue to treat the Central Asian variety as a separate species, C. songaricum; it is called suoyang (Chinese: 鎖陽) in China, where it is extensively collected as an herbal remedy.

The Latin binomial Cynomorium coccineum was first published by Linnæus in Species Plantarum (1753). Its placement in the Saxifragales was resolved in 2016 with the help of nuclear, plastid, and mitochondrial sequences obtained from next-generation sequencing.

Common names include the misleading "Maltese fungus" or "Maltese mushroom"; also "desert thumb," "red thumb," tarthuth (Bedouin), and suoyang (Chinese). During the 16th century, the Knights of Malta incorrectly believed it to be a fungus, and it became known as fungus melitensis, or "Maltese mushroom."

Cynomorium coccineum L. is a herbaceous and perennial holoparasitic plant species with a large geographical distribution range including the western Mediterranean and extending over northern Africa and the Arabian Peninsula until western China. It is a perennial succulent parasitic herb with a reddish-brown coloration, predominantly submerged in sand and lacking chlorophyll. Traditionally, it has been used in ethnic medicine to treat various diseases.

Cynomorium coccineum var. coccineum is found from the Atlantic coastal desert in Mauritania and Western Sahara, through Morocco, the Canary Islands, southern Iberia, the Balearic Islands, Algeria, Corsica, Sardinia, Sicily, southern Italy, Malta, Tunisia, Libya, Egypt, the Arabian Peninsula, Somalia, Iran and Afghanistan. Cynomorium coccineum var. songaricum is found in Central Asia and Mongolia, where it grows at high altitudes. As a rare or local species, it grows in dry, rocky or sandy soils, often in salt marshes or other saline habitats close to the coast.

Suo Yang plants are holoparasitic and have no leaves, so they cannot produce energy by themselves. They usually parasitise the roots of other plants, such as those of the Nitrariaceae family in China.

Common Preparations and Dosage Forms

These species are used in health foods, tea, and cosmetics. In research settings, preparations have included dried stem decoctions, aqueous extracts, ethanol/methanol extracts, ethyl acetate fractions, and standardized polysaccharide or flavonoid isolates. Several traditional C. songaricum prescriptions have been included in the Chinese Pharmacopoeia as modern clinical medications. In contemporary supplement commerce, the plant is sold as encapsulated dried herb powder, standardized hydroalcoholic extracts, and concentrated (e.g., 10:1) extracts, though human clinical dosing data from controlled trials are limited.

2. Historical and Traditional Use

Mediterranean and European Antiquity

Cynomorium coccineum is an edible, non-photosynthetic plant widespread along the coasts of the Mediterranean Sea. The medicinal properties of the "Maltese mushroom"—one of the oldest vernacular names used to identify this species—have been kept in high regard since ancient times to the present day.

Cynomorium coccineum has been known and described for centuries in the Middle East, North Africa and Europe, first as a fungus then as a plant. The therapeutic uses of C. coccineum, the Maltese mushroom, seem to become clearly traceable since the Canon of Medicine by Avicenna. The Arabs and other Muslims of the Middle Ages were the most sophisticated medical practitioners of their time and well acquainted with experimental methods. Clinical and therapeutic works written in Arabic and translated into Latin found their way into Europe's best medical schools. The massive and authoritative Canon of Medicine by Ibn Sina (Avicenna) was translated in the 12th century and served as the standard textbook for medical training in European universities even well into the 18th century.

The consensus of recommended therapeutic uses of Cynomorium across the centuries is treating haemorrhages of all kinds as well as diarrhoea and dysentery. Styptic and astringent drugs such as Cynomorium, Cytinus, gall apples and many others were selected for their protein-linking capacity leading to the formation of a protective layer on the mucous membranes, which can be used to reduce the secretion of water and electrolytes in case of diarrhoea, dysentery and external bleedings.

It has been used for similar purposes in the east and west of its range: crusaders carried dried spikes to help them recover from their wounds. Other traditional uses have included treatments for apoplexy, dysentery, sexually transmitted diseases, hypertension, vomiting and irregular menstruation.

The Knights of Malta

The Knights of St John valued Cynomorium coccineum for its supposed medicinal properties. They introduced the plant to the European medical practices of the time and even traded the ground plant powder to cure various conditions. The Malta Medieval Order protected and used C. coccineum to cure the bleeding wounds of knights struck in battle, and dysentery, rather frequent at that time because of the precarious hygienic conditions. During the 16th century, the Knights of Malta greatly prized the plant and sent samples of it to European royalty. The plant was exploited as an auxiliary income by the Grand Masters of the Knights Hospitaller and presented as a noble gift to European personalities. Cynomorium coccineum became an important pharmaceutical commodity after the Siege of Malta but its importance decreased in the 18th century and now is considered obsolete.

Arabian and North African Traditions

C. coccineum growing in northern Africa and the Mediterranean region is regarded in Arabian medical practice as the "treasure of drugs." Botanist Loutfi Boulos reports that North African medical tradition regards the entire plant as an "aphrodisiac, spermatopoietic, tonic, and astringent." Botanist James Duke cites tarthuth's traditional use as a medicinal tea in Qatar. C. coccineum is also known in Arab countries as Tharthut, Tarthoorth, or Zobb el Ard. In traditional medicine, it is mixed with butter and consumed to treat obstructions of the bile duct.

Traditional Chinese Medicine (Suoyang)

Suo Yang was mentioned by Tao Zongyi (1329–approximately 1410) in his Bencao Yanyi Buyi (Supplement and Expansion of Materia Medica, 1347). The stem of Cynomorium songaricum is a traditional Chinese medicine reputed to have tonic effects. It is used to tonify the yang (treat impotence and backache), strengthen the tendons, and nourish the blood to alleviate the blood-deficiency type of constipation (typically occurring with old age).

Cynomorium songaricum Rupr. has a long history of being widely used as a functional food and medicine by different ethnic groups worldwide; it is used to treat impotence and premature ejaculation and traditionally used as a natural source of tonic food. Traditional Chinese medicine regards C. songaricum as an outstanding kidney-yang and tonifying remedy. Additionally, it nourishes the essence and blood, as well as moistening the intestines and bowel movements.

It was an ingredient in the recipe for Hidden Tiger Pills (Chinese: 虎潛丸; pinyin: hǔqián wán), used for impotence and weak legs.

Species of the genus Cynomorium, including C. songaricum Rupr. and C. coccineum L., have a long history of use in traditional medicine to treat various ailments such as impotence, premature ejaculation, kidney-yang deficiency, spermatorrhea, colic, and stomach ulcers. The ethnomedical uses of C. songaricum and C. coccineum in Saudi Arabia, China, Afghanistan, Mongolia, and Iran for several types of ailments have been recorded.

3. Phytochemistry: Key Constituents and Active Compounds

The major constituents of Cynomorium plants have been revealed to be phenolic compounds, steroids, triterpenes, and others. At least 76 bioactive compounds, including flavonoids, terpenoids, steroids, organic acids, saccharides, glycosides, and phloroglucinol adducts, have been isolated and identified in C. songaricum. In total, 98 compounds have been isolated and identified from C. songaricum, including flavonoids, terpenes, steroids, and other compounds.

For C. coccineum, a total of 29 compounds—including 8 triterpenoids, 6 flavonoids, 4 fatty acids, 8 phenolic acids, 1 anthraquinone, 1 nucleoside, and 1 sterol—were detected and identified or tentatively identified for the first time.

Phenolic Acids and Flavonoids

A validated LC-MS/MS analytical method identified twelve components including phenolic acids (gallic acid, protocatechuic aldehyde, protocatechuic acid, and ferulic acid), flavonoids (catechin, epicatechin, rutin, luteolin, luteolin-7-glucoside, and epicatechin gallate), the anthraquinone emodin, and the triterpene ursolic acid in Cynomorii herba. Gallic acid and cyanidin 3-O-glucoside were identified as the main constituents in Mediterranean specimens. Flavonoids and polysaccharides have significant antioxidant and anti-inflammatory properties.

Triterpenes and Sterols

From the stems, catechin, flavan-3-ol oligomers and tannins were isolated, as well as the triterpenes ursolic acid, acetyl ursolic acid, and malonyl ursolic acid hemiester. From the aerial parts, palmitic acid, sucrose, β-sitosterol palmitate, β-sitosterol and β-sitosterol glucoside (daucosterol) were also isolated. C. coccineum contains many active ingredients including anthocyanic glycosides, triterpenoid saponins, and lignans.

Polysaccharides

Polysaccharides are the main effective components of C. songaricum's stem that perform biological activities and have positive impacts on immune enhancement. The monosaccharide composition of one isolated polysaccharide fraction (CSP-III) included mannose, glucuronic acid, galacturonic acid, rhamnose, glucose, galactose, and arabinose at a defined molar ratio.

Chemical Instability

Some chemical constituents in Cynomorium plants are unstable, implying that the chemical components of herbal medicines produced under different conditions may be variable. This is a relevant consideration for standardization of commercial preparations.

4. Pharmacology and Mechanisms of Action

4.1 Antioxidant Activity

Evaluation of the antioxidant potential of fresh specimens of C. coccineum picked in Sardinia, Italy, using multiple assay systems (DPPH, FRAP, TEAC, ORAC-PYR) demonstrated antioxidant capacity in both aqueous and methanolic extracts. Total phenolics and flavonoids were also determined; gallic acid and cyanidin 3-O-glucoside were identified as the main constituents. Research in China has shown that Cynomorium, like green tea, has "very strong antioxidant effects."

These findings are based on in vitro chemical assay systems and should be interpreted as preliminary; they do not constitute evidence of equivalent antioxidant benefit in humans.

4.2 Reproductive and Sexual Health

Biological and molecular pharmacologic studies of Cynomorium plants have demonstrated that these plants have the potential to help develop therapies that affect male reproductive function.

A significant animal study examined spermatogenesis in rats: Cynomorium songaricum has been used in traditional Korean medicine to treat male infertility, including sexual dysfunction, by improving kidney function. Glial cell-derived neurotrophic factor (GDNF) produced by Sertoli cells induces the proliferation of undifferentiated spermatogonia. The effects of C. songaricum on sperm parameters and GDNF expression were investigated after administration of the extract to 8-week-old male Wistar rats for 56 consecutive days (1.0 g/kg/day, p.o.), the period of sperm formation in the rat. The CS-treated animals showed significant increases in epididymal sperm count and absolute testes weights compared to the control group. CS also increased the expression of GDNF at both the mRNA and protein levels. These results suggest that CS may improve male fertility by enhancing spermatogenesis and GDNF expression.

A further rat study in oligoasthenospermia (OAS) models found: CS can significantly improve sperm concentration, sperm motility, and serum testosterone level in OAS rats, probably by inducing the expression of GDNF in the rat Sertoli cells, promoting the proliferation of undifferentiated spermatogonial cells, and enhancing spermatogenesis.

The effect of C. songaricum flavonoids (CSF) on reproductive injury and testicular mesenchymal stem cell viability in male mice and TM3 cells was also investigated, exploring the possible association between these effects and the testosterone synthesis pathway. Mice were administered cyclophosphamide to induce reproductive damage, followed by CSF administration.

All evidence in this domain is currently from in vitro and animal studies. No controlled human clinical trials on Cynomorium and reproductive function have been published in the peer-reviewed literature identified in this review.

4.3 Neuroprotective Effects

C. songaricum is a herb with promising neuroprotective effects, a function that is majorly attributed to its flavonoids.

In a mouse study on hippocampal neurogenesis, the effects of C. songaricum extract (CSE) on novel object recognition, cell proliferation and neuroblast differentiation in the dentate gyrus of mice were assessed using BrdU and polysialylated neural cell adhesion molecule (PSA-NCAM). Serum corticosterone levels were also measured. Male C57BL/6J mice were divided into 3 groups: vehicle-treated, 40 mg/kg CSE-treated, and 100 mg/kg CSE-treated. The vehicle and CSE were given once daily for 3 weeks. Administration of CSE significantly increased the preferential exploration of new objects in these mice.

In ovariectomized rat models relevant to post-menopausal cognitive decline: CSE significantly enhanced the number of CA1 pyramidal neurons in hippocampal slices obtained from OVX rats. CSE was found to have an ameliorating effect on neuronal cell viability and a neuroprotective influence on the hippocampal part of the OVX rats. Mechanistically, the expressions of p-p38MAPK and p-ERK levels were significantly downregulated by CSE intervention, whereas BDNF and p-CREB were significantly upregulated by CSE compared to the control.

At the triterpenoid level, a further investigation led to the isolation and identification of four previously undescribed triterpenoids, together with 20 known compounds, whose structures were elucidated by extensive spectroscopic analysis. Sixteen compounds showed significant neuroprotective effects against glutamate-induced or oxygen-glucose deprivation-induced SK-N-SH cell death.

In an Alzheimer's disease model, a study explored the effects of total flavonoids of C. songaricum on an AD model by focusing on changes in the BDNF/TrkB axis. The AD model was induced in rats via transcranial injection of Aβ1-42 and AD symptoms were treated with CS at three doses. Donepezil was used as the positive control. Changes in rat memory and learning abilities, brain histological outcomes, apoptosis, production of neurotransmitters, BDNF/TrkB axis, and apoptosis-related markers were measured. Injection of Aβ1-42 induced cognitive dysfunction in AD rats.

All neuroprotective findings are from animal and cell-culture models. No human clinical trials in this domain have been identified in the peer-reviewed sources reviewed here.

4.4 Anti-fatigue and Exercise Performance

C. songaricum contains a variety of biologically active compounds that can improve the sexual function, immunity, and hypoxia resistance of the body, and produce other pharmacological effects like reducing stress and fatigue.

Significant and dose-dependent antioxidant and anti-fatigue effects of C. songaricum flavonoids (rutin, catechin and isoquercitrin) on swimming rats were observed during 10 days of swimming exercise. Cynomorium has been shown to increase physical endurance and stamina, and is thought by experts to have good prospects in the treatment of fatigue. In an animal study with trained swimming mice, C. songaricum improved physical endurance. The researchers proposed that the Cynomorium-treated group had an increased ability to consume and utilize oxygen.

Again, this evidence is confined to animal models and extrapolation to humans requires caution.

4.5 Antidiabetic / Hypoglycaemic Effects

The crude extracts and pure compounds from C. songaricum and C. coccineum exhibited a wide spectrum of in vitro and in vivo pharmacological activity, including anti-diabetic activity. The flavan-3-ol oligomers isolated from the stems have been shown to inhibit the activity of α-glucosidase, an enzyme critical to post-prandial glucose absorption—a well-established antidiabetic mechanism shared by drugs such as acarbose. This finding is from in vitro enzyme-inhibition experiments and has not been validated in human clinical trials.

4.6 Immunomodulatory Effects

The capacity of the isolated polysaccharide fraction CSP-III, at various concentrations, to stimulate the proliferation of mouse spleen lymphocytes in vitro was assessed, and the influence of CSP-III on cell proliferation was examined using RAW264.7 mouse mononuclear macrophages as a model. Modern pharmacological studies have shown that the extract has the ability to promote cell regeneration and metabolism and enhance immune regulatory function. These findings are preclinical.

4.7 HIV-1 Protease Inhibition

From CH₂Cl₂ and MeOH extracts of the stems of C. songaricum, ursolic acid and its hydrogen malonate were isolated as inhibitors of HIV-1 protease, with 50% inhibitory concentrations (IC₅₀) of 8 and 6 μM, respectively. Among various synthesized dicarboxylic acid hemiesters of related triterpenes, inhibitory activity tended to increase in the order of oxalyl, malonyl, succinyl, and glutaryl hemiesters for triterpenes such as ursolic acid, oleanolic acid, and betulinic acid. The most potent inhibition was observed for the glutaryl hemiesters, with an IC₅₀ of 4 μM. From the water extract, flavan-3-ol polymers consisting of epicatechin as their extender flavan units were also found to be potent inhibitory principles against HIV-1 protease. These are in vitro biochemical findings only; there is no clinical evidence of antiviral activity in humans.

4.8 Anticancer Activity

To understand the potential anticancer activity, researchers screened C. coccineum and C. songaricum using three different extracts of each species, evaluating their ability to decrease survival rates of five different cancer cell lines. In vitro, the ethanol extract of C. coccineum inhibited cancer cell proliferation, survival, migration, invasion, and colony formation. In vivo, the water extract of C. coccineum inhibited tumor growth and prolonged animal survival.

Mechanistically, CS3-induced autophagosome formation was found and confirmed by electron microscopy and the high expression levels of microtubule-associated protein-1 light chain 3-II (LC3II), a marker protein of autophagy. CS3 activated and increased the pro-apoptotic mitochondrial proteins BNIP3 and BNIP3L at the mRNA and protein levels. The constituents of CS3 down-regulated anti-apoptotic BCL2, and then released autophagic protein Beclin-1.

Further investigation showed that treatment with C. coccineum induced the overexpression of the tumor suppressor Foxo3 and other molecules involved in inducing autophagy. These results showed that the C. coccineum extract exerts its antiproliferative activity through the induction of cell death pathway. Thus, Cynomorium plants appear to be a promising source of new antineoplastic compounds.

All anticancer findings are preclinical (in vitro and animal). There are no human clinical trials of Cynomorium for cancer treatment.

5. Scientific Evidence by Health Area: Strength Assessment

Reproductive Health and Male Fertility

• Study type: Multiple animal studies (rat, mouse models) and in vitro cell models.
• Findings: CS can significantly improve sperm concentration, sperm motility, and serum testosterone level in oligoasthenospermia rats, probably by inducing the expression of GDNF in the rat Sertoli cells, promoting the proliferation of undifferentiated spermatogonial cells, and enhancing spermatogenesis.
• Evidence strength: Preclinical only. No published randomized controlled trials in humans have been identified. Animal data are mechanistically interesting but cannot be directly applied to clinical claims.

• Evidence strength: Preliminary. Entirely preclinical.

6. Dosages Reported in Research Studies

The following doses are reported as used in cited research, not as recommendations.

• In a rat spermatogenesis study, C. songaricum extract was administered at 1.0 g/kg/day orally for 56 consecutive days.
• In a mouse hippocampal neurogenesis study, doses of 40 mg/kg and 100 mg/kg CSE were administered once daily for 3 weeks.
• In a 90-day repeated oral toxicity study in rats, doses of 1.04, 2.08, or 4.16 g/kg were administered.
• In the acute toxicity test, the maximum tolerable dose of Suo Yang was found to be greater than 15 g/kg in mice.

No peer-reviewed human clinical trials with defined therapeutic dosages for any indication have been identified in the sources reviewed. In traditional Chinese medicine practice, the dried stem is typically used in decoctions, but exact dose ranges from authoritative pharmacopoeial monographs were not available in the sources reviewed.

7. Body Systems and Health Areas Associated with Cynomorium

Based on both traditional use and preclinical evidence, Cynomorium has been associated with the following body systems:

• Reproductive system: Male fertility, spermatogenesis, testosterone, erectile function, and female reproductive health (irregular menstruation).
• Nervous system: The extract has been shown in animal studies to enhance immune regulatory function and has anti-aging properties. Neuroprotective effects and hippocampal neurogenesis have been demonstrated in animal models.
• Immune system: Polysaccharide fractions have shown immunomodulatory effects in in vitro models.
• Gastrointestinal system: The consensus of recommended therapeutic uses across centuries includes treating haemorrhages and diarrhoea and dysentery, attributed to astringent tannin content.
• Metabolic / endocrine: Anti-diabetic and α-glucosidase inhibitory activity in preclinical models.
• Musculoskeletal: Traditional use in TCM for strengthening tendons and muscles, reflected in its inclusion in Hidden Tiger Pills.

8. Safety Considerations

Animal Toxicology Studies

C. songaricum (Suo Yang) is most commonly used to treat fatigue, protect the liver, and invigorate kidneys in Northwest China. Given the wide medicinal utilization and lack of safety evaluation, one published study evaluated its acute toxicity, genetic toxicity, and 90-day repeated oral toxicity.

In the acute toxicity test, no abnormal behaviour or mortality was found in mice. The results suggest that the maximum tolerable dose of Suo Yang is greater than 15 g/kg. In the genotoxicity studies, no revertant colonies were produced in vitro. In the in vivo assays, no increased frequencies of micronuclei or structural abnormalities of spermatocyte chromosomes were found. In the 90-day repeated oral toxicity study, no significant toxicological manifestations were observed in haematological parameters or clinical and pathological examinations. In summary, these results suggest that Suo Yang at the given doses does not cause adverse effects in animals. Thus, Suo Yang can reasonably be considered a safe herbal medicine based on this preclinical data.

Chemical Variability as a Safety Factor

Some chemical constituents in Cynomorium plants are unstable, implying that the chemical components of the herbal medicines produced under different conditions may be variable. This instability means that the actual composition of commercial products can differ substantially from that of the plant material used in laboratory studies, with implications for both efficacy and safety assessment.

Absence of Human Safety Data

The toxicity of Cynomorium has not been well studied in humans. It should be noted that it was used as both a food and medicine in traditional contexts, which is consistent with a relatively benign profile over long periods of use. However, the absence of systematic human safety evaluation means that drug interaction profiles, effects in specific populations (pregnant or nursing women, individuals with hormonal conditions, those on anticoagulants), and long-term effects at supplemental doses remain undefined in the peer-reviewed literature.

Traditional Contraindications

Based on TCM theory, Cynomorium (suoyang) is classified as a warm, yang-tonifying herb and has traditionally been considered unsuitable for those with yin deficiency with heat signs, or those with diarrhoea, as its moistening intestinal effects are considered inappropriate in those situations.

9. Current Status in Research and Commerce

Cynomorium coccineum subsp. coccineum is a holoparasitic plant well known in ethnopharmacology, although its current use as a curative remedy is reported only in some ethnic groups of North Africa and the Arabian Peninsula. Often known as "Maltese mushroom" due to its unique appearance and the absence of chlorophyll, C. coccineum is present in almost all of the Mediterranean Basin. It is only recently that a few research groups have begun to look for confirmation of some of its traditional uses to highlight previously unknown biological activities.

These compounds show good application prospects in anti-tumor, antioxidant, anti-aging, anti-fatigue, anti-diabetes, and other aspects. Although extensive progress has been made in the basic research of C. songaricum, further research is still needed to enhance the understanding of its mechanism of action and explore more unknown compounds.

The overall body of evidence on Cynomorium remains substantially preclinical. The vast majority of pharmacological studies have been conducted in cell cultures and animal models, predominantly in China and South Korea. Human clinical trials are absent from the peer-reviewed record identified in this review. The gap between the rich traditional use across millennia and the current state of controlled human evidence is substantial, and the botanical's therapeutic claims—while historically consistent across cultures—await the rigorous validation of properly designed clinical studies.
