Fructus Sophorae Extract, derived from the flower of the Sophora japonica tree, a medium-sized deciduous tree predominantly found in China, Japan, Korea, Vietnam, and other regions, is renowned for its abundant flavonoids, notably rutin and quercetin. These flavonoids endow the extract with potent antioxidant, anti-inflammatory, and vascular protective qualities. Consequently, the extract is extensively utilized in traditional medicine and contemporary health supplements to enhance cardiovascular health, fortify blood vessels, and bolster overall well-being.

Sophora japonica, belonging to the Fabaceae family, has a rich history in medicinal use, documented in ancient Chinese medicinal texts and currently listed in both the Chinese Pharmacopoeia and European Pharmacopoeia. Within Asia, particularly in China, the flower buds (Flos Sophorae Immaturus) and fruits (Fructus Sophorae) of S. japonica are widely employed to treat a variety of conditions, including hemorrhoids, hematochezia, hematuria, hematemesis, hemorrhinia, uterine or intestinal hemorrhage, arteriosclerosis, headache, hypertension, dysentery, dizziness, and pyoderma.
