This article explains everything you need to know about senna tea.
Senna is an herbal medicine made from the leaves, flowers, and fruit of a large group of flowering plants in the legume family (1).
Extracts and teas made from senna plants have long been used as laxatives and stimulants in traditional herbal medicine (1).
Originally from Egypt, senna is now grown worldwide, including countries like India and Somalia.
Most commercial products are derived from Cassia acutifolia or Cassia angustifolio, commonly known as Alexandrian and Indian senna, respectively (1).
Today, senna is most often sold as a tea or over-the-counter constipation supplement, but its also occasionally used in weight loss pills and drinks.
Senna is an herb in the legume family thats often used as a laxative. Additionally, its sometimes added to weight loss supplements.
The most common application for senna tea is to stimulate bowel movements and alleviate constipation.
The primary active compounds in senna leaves are known as senna glycosides, or sennosides. Sennosides cannot be absorbed in your digestive tract, but they can be broken down by your gut bacteria (1).
This breakdown of sennosides mildly irritates the cells in your colon, an effect that stimulates intestinal movement and produces a laxative effect.
Senna is an active ingredient in many popular over-the-counter laxative medications, such as Ex-Lax and Natures Remedy. For most people, it will stimulate a bowel movement within 612 hours (2).
Because of its laxative effects, some people use senna tea to prepare for colonoscopies (3).
Some people may also use senna tea to relieve discomfort associated with hemorrhoids.
Hemorrhoids are swollen veins and tissues in the lower rectum that can cause bleeding, pain, and itching. Chronic constipation is a major cause, and minor bouts of constipation can irritate preexisting hemorrhoids (4).
However, sennas efficacy for relieving hemorrhoid symptoms has not been thoroughly studied.

Yet, no scientific evidence supports using senna tea for any detox, cleanse, or weight loss routine.
In fact, using senna tea in this manner may be very dangerous.
Senna is not recommended for frequent or long-term use, as it may alter normal bowel tissue function and cause laxative dependence (2).

Its considerably more difficult to determine a precise dose because the concentration of sennosides varies dramatically depending on how long your tea steeps.

In this case, the safest approach is to follow the package instructions for preparation and consumption. Never take more than directed on the label.

If youre preparing senna tea from scratch, steep 12 grams of dried senna leaves in hot water for 10 minutes. Avoid drinking more than 2 servings per day (7).
