Glycine Soja, or wild soybean (previously G. ussuriensis) is an annual plant in the legume family. It is the closest living relative of soybean, an important crop.
- It is commonly used in bath oil and soap making, as well as for skin conditioning and skin firming because it is a natural emollient and moisturizer.
- Soybeans contain the isoflavones and types of phytoestrogen which are considered by some to be useful in the prevention of cancer and by others to be carcinogenic and endocrine disruptive.
Although glycine soja is generally considered safe and is used in many moisture-rich products, there are some studies that show that it acts as an oxidant (stimulating nitrate synthesis) as well as that it blocks formation of new blood vessels (antiangiogenic effects). Some studies show it to act as an inhibitor of the activity of substances in the body that regulate cell division and cell survival (source). Many people experience soy allergies, so use of any soy product should be used with caution if there are known allergies.
There is also a 2001 study that links the phytoestrogen properties of glycine soja to breast cancer in animals. A 2006 study reiterated these findings, but most literature on the ingredient is positive.
