Astragaloside IV inhibits vascular calcification through estrogen receptor alpha.

Abstract

Astragaloside IV (As-IV), a key component of traditional Japanese Hozai tonics, has a steroid skeleton like estrogen. It inhibits vascular calcification via estrogen receptor α, offering cardiovascular benefits. However, its estrogen-like properties promote breast cancer cell proliferation. Targeted research is needed to optimize cardiovascular preventive effects without adverse effects.
