Description Wild Yam is a perennial, twining, tuberous climbing vine that grows about 15 ft. tall. The plant is found growing in thinly wooded bluffs, typical savannas and sandy savannas, woodland borders, typical thickets and sandy thickets, moist sand prairies, power line and railroad clearances in wooded areas, and fence rows, borders of bogs, swamps, marshes, river and lake margins, creek bottoms, rocky soils, moist or dry woods, hammocks, limestone or talus slopes and roadsides. The plant grows abundantly in a wide variety of soil types, including light, medium, and heavy soils that are well-drained. It cannot grow in the shade and requires moist soil. The plant has long, branched, crooked, and woody root, the taste being dull, afterwards acrid. Plant has pale-brown, knotty, woody, cylindrical tubers which are light brown outside and white fibrous inside. Stems are little branched, leafy, grooved or narrowly winged, mostly hairless, lack tendrils and twine around other vegetation for support, and spreads by seed or branching rhizomes. Leaves Leaves are mostly alternate, though may be whorled or nearly so near the base of the plant, 1 to 5 inches long, ¾ to 5 inches wide, heart-shaped, sharply pointed at the tip, with 7 to 11 deep veins radiating from the base and a hairless stalk up to 6 inches long that may be ridged or narrowly winged, sometimes with a few hairs where the stalk joins the blade. Leaf edges are toothless and sometimes a bit wavy. The upper surface is hairless and the lower variously hairy, sometimes hairless or glandular. Color is light to medium green. Flower Wild Yam is dioecious, producing vines with either all male flowers or all female flowers. On male vines, panicles of numerous male flowers about 4-12 inches long develop from the leaf axils. Male flowers are arranged in small clusters of 1-3 along the branches of each panicle. Individual male flowers are about 1/8 inches (3 mm.) across, consisting of 6 whitish green or yellowish green tepals and 6 fertile stamens. On female vines, racemes of 5-15 female flowers about 3-9 inches long develop from the leaf axils. Individual female flowers are about 1/8 inch (3 mm.) across and 1/3 inches (8 mm.) long, consisting of 6 whitish green or yellowish green tepals and a large inferior ovary with 6 infertile stamens. The blooming period occurs during early summer. The female flowers are followed by 3-celled seed capsules that are ovoid in shape and about 1 inch long. These capsules are strongly 3-angled and become golden green as they mature. Each cell of the capsule usually contains 2 seeds (less often, only 1). The flattened seeds have broad membranous wings; they are distributed by the wind. Health benefits 1. Blood sugar regulation Wild yam consists of a chemical called dioscoretine, which some people think helps with the regulation of blood sugar levels. Wild yam could be useful in regulating blood sugar levels in people with diabetes. However, the effect of dioscoretine on blood sugar has only been researched in animals so far. It is unclear whether it would have the same effect in humans. 2. May Help Reduce Photo-aging Research indicates that the disogenin found in wild yam extract may have a "depigmenting effect." This means it could help with issues such as melasma, melanodermatitis and sun lentigo issues that eventually result in hyperpigmentation. Hyperpigmentation is harmless and rather common, but it can be frustrating since it is a skin condition that develops, rather noticeably, as darker patches of skin. 3. Rheumatoid arthritis Traditional medicine practitioners believe that wild yam has anti-inflammatory properties and use it to treat rheumatoid arthritis. Rheumatoid arthritis is a chronic condition that causes inflammation of the joints. This can cause pain and stiffness that limits mobility in people with the condition. It is possible that wild yam might reduce this inflammation and have a positive effect on symptoms, but there is little evidence to support this. 4. Cramps and muscular pain Wild yam is believed that it has anti-spasmodic properties, which are substances that reduce muscle spasms. This anti-spasmodic property means that wild yam might be useful for reducing cramps and muscular pain related to premenstrual syndrome (PMS). However, more research is needed to support this. 5. Menopause Management Wild yam may be useful for managing menopause symptoms, though scientific evidence for its benefits is weak at this time. Its strong estrogenic and progesterone-like effects may help to balance hormone swings of menopause and decrease heavy bleeding or unpredictable spotting during peri-menopause. Wild yam may also help reduce irritability, and its anti-inflammatory benefits might offer relief of joint pain that often accompanies menopause. 6. Breast health Wild Yam is one of the leading ingredients in most breast enhancement supplements/creams since it encourages healthy breast tissue. Wild Yam does not raise your estrogen levels. Wild Yam Root makes breasts larger by using the natural progesterone. It is famous for balancing female hormones and assists in the natural development of breast growth. 7. High Cholesterol Researchers have wondered that taking wild yam may help lower cholesterol levels, although research has shown mixed results. Diosgenin seems to block the body from absorbing cholesterol, at least in animal studies. But in research of people, cholesterol levels have not gone down - although fats in the blood (triglycerides) have decreased. More research is needed to determine whether wild yam would help people with high cholesterol. |
