Senna Stems are a by-product collected during the harvest of Senna plants, and though less concentrated in sennosides than leaves or pods, they are widely used in the herbal and extract industry. After being air-dried and cleaned, Senna stems are supplied as whole or cut pieces, offering cost-effective raw material for supplement blending and extract manufacturing. They are also commonly used as filler in herbal teas and other natural health formulations, making them a versatile ingredient in the herbal supply chain.
