Senna leaves are cold and can cause diarrhea after taking them. If this diarrhea problem is serious, it will damage the righteousness. Patients with weak constitution and long-term constipation are not suitable for taking senna.
Senna leaf is not suitable for constipation in the elderly, because although Senna leaf has the function of catharsis, it can also help abdominal qi flow smoothly, but it can not fundamentally solve the problem, but will lead to an increase in the loss of yin deficiency in the body. The elderly suggest that Chinese herbal medicines such as Cistanche deserticola, Cynomorium songaricum and Rehmannia glutinosa should be taken together with Senna leaves, which is better for health care.
