This flowering plant has dark green vines and leaves that vary in size and shape — though it’s best known for its tuberous roots, which have been used in folk medicine since the 18th century to treat menstrual cramps, coughs, and upset stomachs ( 1, 2). From the our study results, all these antioxidant minerals (Cu, Zn, Mn, Fe, and Se) and Cr intakes can be supplemented by incorporating Korean yam powder supplements in addition to daily meals. With taking the daily recommended supplementation intake of Korean yam powder (50 g), Zn intake can supplemented up to 18.5 and 23.8% for men and women of recommended intake (RI) of dietary reference intakes of Korea (KDRIs) without any upper limit (UL) toxicity (only 0.6~4.8% UL intake). Mn intake can be supplemented up to 25.0% for men and 22.9% for women still without any UL consideration (only 1.8~9.1% UL intake). Fe intake from daily yam supplementation was up to 49.4% and 55.6% for men and women recommended intake (RI) of KDRIs with only 0.7~9.9% UL which is beneficial for intake-wise as well as upper limit-wise. Cu intake is very much the same beneficial with 32.5% RI intake but very low level of UL, only 1.1~2.6% UL level. The most abundant supplementation from the daily intake of yam powder supplementation was shown in Se intake which is about 195% RI with upper limit of 24% on average. For the Cr supplemental intake from yam products, average 197% (for men) and 286% (for women) of RI level was analyzed, specially product B showed a considerate level of high contents (768% and 1153% RI for men and women) which needs a special caution to take it. Tohda C, Yang X, Matsui M, et al. Diosgenin-rich yam extract enhances cognitive function: a placebo-controlled, randomized, double-blind, crossover study of healthy adults. Nutrients. 2017 Oct 24;9(10): pii: E1160. View abstract.They can be used all over the body to produce a natural glow. They’re gentle on skin, deep clean in just a few seconds, and are great makeup removers. They’re also 100% biodegradable! Several rat studies have observed that yam powder reduced inflammation related to several illnesses, including colon cancer, irritable bowel syndrome (IBS), and stomach ulcers ( 16, 19, 25, 26). In a rat study, rats were given a dose of yam water or yam powder. As a result, the rats experienced a significant decrease in their fasting blood sugar as well as a decrease in their hemoglobin A levels, which measures blood sugar control. My sister moved recently and left me some dried foods she had at her house including yam flour. I have never used yam flour before so I'm not sure what can be done with it. There is limited evidence that yam extract may be a helpful remedy for some of the unpleasant symptoms of menopause.

Put the yam into a mortar and pound it with a pestle until it's smooth. Set a large mortar on your work surface and put enough of the yam chunks into it to cover the bottom. Then, push down on the yams with the pestle to break them into small pieces. Keep pounding down and add a few more yam chunks as you work. Pound the yam until it's completely smooth and stretchy. [15] X Research sourceWild yam may interact with other medications, and consuming large amounts can lead to side effects. It is, therefore, necessary to speak to a doctor before taking wild yam. Fe: Fe intake from yam daily supplementation is about 0.3~4.5 mg/50 g yam powder intake ( Table 3C). This amount gives the range of up to 49.4% for men and 55.6% for women for daily RI Fe intake of KDRIs. This value compensates more than 1/2 of the daily Fe KDRI level. Upper limit (UL) for Fe is within the range of 0.7~9.9% which is still fairly safe. It’s important to remember that this was a small study, and more evidence is needed to confirm these health benefits. Reduced cholesterol levels. In a 4-week study in rats, diosgenin extract significantly lowered total and LDL (bad) cholesterol levels ( 18).

Furthermore, another study in rats found that supplementing with yam flour reduced the rate of blood sugar absorption, which led to improved blood sugar control. These effects are attributed to the resistant starch and fiber in yams ( 29).

Kaur, B., et al. (2021). Current highlights on biochemical and pharmacological profile of dioscorea alata: A review. They have many other reported health benefits, though most of the research on this has been on compounds extracted from the yam root. Research is in its early stages. But it has looked at these possible benefits: Zakharov, V. N. [Hypolipemic effect of diosponine in ischemic heart disease depending on the type of hyperlipoproteinemia]. Kardiologiia. 1977;17(6):136-137. View abstract. Further studies are needed on this root’s interactions with other medications and supplements ( 22). summary

Men with prostate cancer should also avoid taking wild yam. There are over 600 species of wild yams. About 12 species are edible. Some people use wild yam as a source of steroids, but the body can't make steroids such as estrogen and DHEA from eating wild yam. This conversion has to be done in a lab. There might be other chemicals in wild yam that act like estrogen in the body.Chronic inflammation is connected to a number of long-term health conditions, like diabetes, obesity, and heart disease. Fortunately, yams are rich in anti-inflammatory antioxidants. Cooking and preparation methods can cause a food’s GI to vary. For example, sweet potatoes have a medium-to-high GI, varying from 44–96, whereas yams have a low-to-high GI, ranging from 35–77 ( 6). Yams are rich in vitamins and minerals and are a nutritious food staple in many places outside the U.S. Consuming wild yam is rare due to its bitter taste. However, it is available in a variety of formulations, including: Zagoya JCD, Laguna J, and Guzman-Garcia J.
