Badia Natural Slimming Tea is an herbal tea that primarily consists of senna leaves. Reference.com indicates that it is designed to aid in weight loss with regular use. The tea is marketed as a detoxifying weight loss aid.
According to Cathy Wong, a naturopathic doctor at About.com, senna has medically proven abilities as a mild laxative. Research has not supported claims that senna tea aids in weight loss or has any detoxifying abilities. Senna tea drinkers do experience less bloating from constipation, and staying regular may promote detoxification, but that claim is not supported by research data. Long-term use of senna beyond two weeks could cause health problems and should be avoided.
