Senna Tea for Constipation

sennaNow let’s take a closer look on this plant. Arabs in the Middle Ages appreciated Senna as a healing plant. In the ninth century it was brought to Europe. For many centuries it has been a valuable and expensive drug.

In the pharmacy, Senna preparations are intended for short-term use in cases of occasional constipation, which can occur due to a diet change, changes in the environment or prolonged inactivity due to injury, or disease and it can’t be eliminated by altered diet and fiber laxatives.

Senna can also be used in problems with hemorrhoids, before the investigations and surgeries when an empty gut is required, as well as after the rectal and anal area operations.

Active Ingredients

The leaves of the Senna contain 3% dianthrone glycosides, sennosides A, A1 and B to F, and a small proportion of anthraquinone glycosides (rein-8-glucoside, rein-8-syphoroside). The leaves contain 2 to 3% mucilage, 0.05% essential oil and flavonoids. Senna pods have a similar composition as leaves, but differ in the content of anthracotic and anthracycline compounds.

The mechanism of Senna’s laxative effect is based on the degradation of sennosides to senidines (aglycones) under the influence of bacterial β-glycosidases in the colon. Because of their hydrophilicity, sennosides are not absorbed in the upper parts of the digestive tract, and digestive enzymes can’t be hydrolyzed, but bacterial enzymes in the colon degrade them to senidines.

Senidines are then metabolized to the active rein-9-anthrone. It accelerates the movement of the colon and reduces the passage time of the excretion. It also reduces the absorption of water and electrolytes into the epithelial cells, and increases the permeability of solid contacts, thus increasing the amount of fluid in the colon. The laxative effect occurs 8 – 12 hours after the consumption of Senna preparation.

The Usage Instructions

senna tea leavesTo prepare the tea, take half to one teaspoon of Senna leaves and pour them with a cup of hot water (150 ml), mix well, let it stand for 10 – 20 minutes and then strain it. Drink a cup of freshly prepared tea once a day, in the evening before going to bed.

The leaves of the Senna can also be poured with a cup of cold water, but in this case, the drug must be soaked for 10 to 12 hours. Then we strain the tea and drink it once a night before sleeping. Some authors say that cold-prepared tea should have less effect, and should not cause cramping or abdominal pain.

Medicinal tea should not be used for a long time; usually it is sufficient to use it twice or three times a week. Also, it should not be consumed too much or drink it too strong because it causes side effects such as abdominal pain, cramps and severe diarrhea, leading to loss of water and electrolytes, especially potassium. The most appropriate dose is the smallest dose that causes the release of soft excretion.


People who are sensitive to Senna can’t use Senna tea for constipation and should avoid it. It shouldn’t be used in the intestinal obstruction, in the inflammation of the gallbladder, inflammatory bowel diseases (Chron’s disease, ulcerative colitis), abdominal pain of unexplained origin or severe dehydration with loss of water and electrolytes.

Side Effects

In rare cases, Senna could cause hypersensitivity reactions (itching, hives, rash). In such cases, we do not use this plant. Hives, abdominal pain, fluid excretion and diarrhea may occur when taking Senna preparations, which may also occur because of overdose.

Severe diarrhea leads to loss of water and electrolytes, especially potassium, which disrupts electrolyte balance in the body. The consequence of potassium loss may be cardiac disorders and muscle weakness.

Due to the secretion of metabolites active substances with urine, you may get yellow or red colored urine if you use Senna preparations, which is not harmful. After you will stop using Senna, the symptoms will disappear.

Interaction with other Medicines

It is not recommended to use Senna with these medicines in the same time.


Long-term use of laxatives should be avoided. Stop using Senna preparations as soon as your digestion is normal again.
