The wild soybean contains soyasaponins, a bioactive compound. Soyasaponins have inflammatory, antimutagenic, anticarcinogenic, antimicrobial properties. Soyasaponin has also been found to inhibit the melanin-creation process.
Two powerful components found in the wild soybean include genistein and diadzein. These two isoflavones are potent antioxidants with anti-inflammatory properties. Genistein in particular has been found to prevent redness caused by UV exposure.
