Condiciones de salud que dioscorea puede ayudar a apoyar.
Dioscorea species contain polyphenols, flavonoids, polysaccharides, and allantoin with documented antioxidant activity. Multiple preclinical studies show increases in SOD, GPx, and reduced glutathione, and decreases in lipid peroxidation markers. A comprehensive PMC review (2022) catalogues these effects across multiple species.
Multiple preclinical studies and a systematic review demonstrate that Dioscorea extracts and key constituents (dioscorin, dioscin, diosgenin, allantoin, polysaccharides) reduce fasting blood glucose and improve glucose tolerance in rodent models of diabetes. A 2022 systematic review in the British Journal of Nutrition found all ten included animal studies showed glycaemic improvement. Human clinical evidence remains limited and more trials are needed.
Preclinical studies with Dioscorea alata extract and dioscorin demonstrate increased bone mineral density and osteoblast differentiation in ovariectomised mouse models. The mechanism involves estrogenic activity via ovarian aromatase upregulation. Human evidence is lacking.
Diosgenin and sapogenin-rich Dioscorea preparations consistently reduce total and LDL cholesterol in multiple animal models via inhibition of intestinal cholesterol absorption and increased fecal excretion. A human study (Dioscorea alata substituted for dietary rice) also observed improvements in serum lipid fractions. No large randomized controlled trials in humans exist.
Diosgenin and dioscin from Dioscorea species show consistent anti-inflammatory activity in animal and cell models, reducing pro-inflammatory cytokines and NF-κB signaling. A 30-day mouse study confirmed significant reduction in inflammatory markers after oral Dioscorea extract. Human clinical evidence is currently absent.
Dioscoreae Rhizoma (dried yam) is listed in the Chinese Pharmacopoeia for treatment of long-term diarrhea. Preclinical evidence from a 2023 animal study shows it improves chronic diarrhea by modulating gut microbiota. Traditional use across TCM is extensively documented.
Dioscorea contains diosgenin, a phytoestrogenic steroidal sapogenin that stimulates estradiol biosynthesis in animal ovarian cell studies and raised serum estrone and estradiol in a 30-day human dietary trial with post-menopausal women. The human body cannot convert diosgenin to progesterone without laboratory synthesis, limiting its direct hormonal action.
Preclinical studies show diosgenin from Dioscorea protects against accelerated senescence in rats, improves cognitive function, and augments bone mineral density. Antioxidant, anti-inflammatory, and phytoestrogenic properties collectively support anti-aging activity in animal models. Human evidence is limited.
Dioscorea constituents, particularly dioscin and diosgenin, have shown cardioprotective effects in animal models via lipid-lowering, anti-atherosclerotic, anti-inflammatory, and estrogen receptor-mediated pathways. Dioscin has been found to attenuate postmenopausal atherosclerosis in animal models. Human evidence is limited.
Dioscorea constituents, particularly polysaccharides and dioscorin, have demonstrated improved insulin sensitivity and reduced insulin resistance in rodent models. Mechanistic evidence points to GLUT4 upregulation, DPP-IV inhibition, and enhanced β-cell function. No robust human trials yet exist.
Diosgenin and dioscin from Dioscorea species demonstrate hepatoprotective effects in multiple animal and cell studies, reducing oxidative stress, liver fibrosis, and inflammatory cytokines. A 2023 PMC literature review catalogues mechanisms including antioxidant activity and gut microbiota modulation. No human liver trials exist.
Dioscorea dioscorin and polysaccharides have shown improvements in metabolic syndrome parameters—including blood glucose, lipids, and adiposity—in obese rodent models. The evidence base is preclinical, with no human trials. A 2022 systematic review flagged metabolic syndrome as a key target area.
Dioscorea alata extract (Dispo85E) promoted osteoblastogenesis, increased bone mineral density, and ameliorated trabecular bone deterioration in ovariectomised mice in a PMC-published study. Animal studies also link dioscorin to enhanced bone mineral density via estrogenic mechanisms. No human RCTs exist.
Diosgenin extracted from wild yam root has been shown in test-tube studies to encourage new skin cell growth and exert a depigmenting effect. A PMC cosmetic study evaluated Dioscorea hispida extract for in vitro and in vivo cosmetic applications. Wild yam extract is a cosmetic ingredient assessed for safety by the FDA/Cosmetic Ingredient Review. Human RCT evidence for anti-aging efficacy is limited.
Dioscorea batatas (Chinese yam) extracts demonstrate gastroprotective effects against ethanol-induced gastric ulcers in mouse models, reducing oxidative stress biomarkers and inflammation. Crude Dioscorea rhizoma extract also showed antioxidant protection in gastric ulcer rat studies. No human ulcer trials exist.
Wild yam has been used for centuries in both Western and Chinese herbal traditions for abdominal cramping, colic, and bloating, owing to its antispasmodic properties on intestinal smooth muscle. Clinical evidence is absent; the rationale is traditional and mechanistic.
Wild yam (Dioscorea villosa) has a strong documented history of traditional use for arthritis and joint inflammation. In vitro and animal studies support anti-inflammatory mechanisms. Human clinical evidence is limited to traditional practice and preliminary findings.
Wild yam and Dioscoreae Rhizoma are documented in traditional medicine—including the Chinese Pharmacopoeia and MSKCC monograph—as used for asthma and coughs, attributed to expectorant and antispasmodic properties on respiratory smooth muscle. Clinical evidence is absent.
Dioscorea is listed in traditional Asian medicine for hypertension (PMC4632431), and its cholesterol-lowering and anti-inflammatory properties provide indirect mechanistic relevance. No human studies specifically examining blood pressure effects of Dioscorea have been conducted.
Wild yam has been used in herbal traditions for digestive complaints including constipation, attributed to its effects on intestinal motility and mucilage content. This is documented in traditional Chinese medicine use of Shanyao. Limited preclinical support exists.
Wild yam has been traditionally regarded as a cholagogue (bile-stimulating herb) used for biliary colic, gallbladder pain, and historically to help pass small gallstones. This use is documented across Western herbalism. Scientific evidence is absent.
Wild yam is documented in traditional Western herbalism as a cholagogue used for biliary colic and gallstone-related complaints. Diosgenin's cholesterol-lowering mechanism is theoretically relevant to gallstone prevention. No clinical studies have been conducted.
Wild yam (Dioscorea villosa) is widely used in traditional and alternative medicine for menopausal hot flashes, leveraging its phytoestrogenic diosgenin content. However, the best-available clinical evidence—a double-blind, placebo-controlled trial in 23 post-menopausal women—found no significant reduction in hot flashes versus placebo.
Wild yam is a well-established antispasmodic herb used traditionally for irritable bowel syndrome, intestinal colic, and bowel cramping. Its smooth muscle relaxant properties provide the pharmacological rationale. Preclinical evidence supports anti-inflammatory and antioxidant intestinal effects, but no human IBS trials exist.
Dioscorea (wild yam species) has extensive traditional use in TCM and indigenous American medicine for menopausal symptoms, primarily via its diosgenin content. However, the human body cannot convert diosgenin to progesterone or estrogen, and clinical RCT evidence for menopausal symptom relief is negative for topical preparations.
Wild yam (Dioscorea villosa) has a well-documented history of traditional use for dysmenorrhea, attributed to antispasmodic effects on uterine smooth muscle. It has been used since at least the 18th century for this purpose. Clinical trial evidence is absent.
Wild yam has been used traditionally as an antispasmodic for muscular spasms and cramps of various types. Its action on smooth muscle is central to this use, documented in multiple herbal traditions. Experimental evidence for skeletal muscle effects exists in animals, but no human trials.
