Senna leaves, different names for Chen Na leaves, Senna leaves and soaked bamboo leaves, come from the narrow leaves or sharp leaves of leguminous plants. Senna leaf, English name, is an irritating laxative, which stimulates intestinal peristalsis through intestinal mucosa and nerves. It's a powerful medicine. I suggest using it as little as possible. It acts on the colon and usually takes effect within a few hours.

It is recommended to drink Guyishu Changqing tea, which is refined from pure natural Chinese herbal medicines. It is natural, safe and has no side effects. It contains no senna leaves and is mild in nature.
