Long-Term Effects of Senna Tea

Senna tea is readily available in many natural food markets and pharmacies as a treatment for constipation. But like all herbs, long-term use can be associated with negative side effects.

What is Senna?

• Senna is a genus of plants, of which one species, senna alexandrina, is commonly used as a laxative. When used as a laxative, senna alexandrina is typically referred to as simply "senna."

What is a Laxative?

• A laxative facilitates bowel movements and may do so in several different ways. Senna is considered a stimulant laxative: It works by causing the colon to contract in order to expel waste matter.

What is Senna Tea?

• Senna tea is not a true tea, but an herbal infusion. Dry senna herb is steeped in boiling water, and the resulting liquid (aka "tea") is consumed. There are several commercially packaged senna "teas" on the market.

Dangers of Laxative Dependency

• Using laxatives can create laxative dependency: If you stop taking a laxative after a long period of use, you might find that the constipation becomes much worse.

Other Senna Side Effects

• Overuse of senna can result in a disruption of electrolyte balance which can cause fainting. Chronic diarrhea, abdominal discomfort and bloating are some of senna's other side effects.
