Organic Senna (Cassia angustifolia) powder is an herb that thrives in tropical areas, though some can grow in more temperate climates. Senna tea can be slightly sweet, but it has strong bitter undertones. It is also not incredibly aromatic. Senna has been marketed as a constipation treatment and a “detox” tea. It’s also often used as a weight loss aid. It’s sometimes used short-term to treat hemorrhoids. The best time for harvesting is between February to March. Finest quality organic senna leaves are selected and cold ground to make organic senna powder.
