♥ More informations of  senna leaf extract:


Senna is a genus of desert flowering plants formerly known as Cassia spp. that consists of

approximately 250 individual species now collectively known as the sennas. Generally speaking,

senna leaf refers to an herb remedy obtained from Senna alexandrina. While many other senna

species have a long historical use in folk medicine, S. alexandrina is the variety best known for

treating constipation.


The purgative action of senna leaf is primarily due to the presence of organic anthraquinones in

the form of various glycosides, including hydroxyanthracene, dianthrone, and naphthalene

glycosides. Senna also contains a group of glycosides referred to as simply sennosides. These

compounds stimulate the smooth muscles that transport digested food through the intestines,

thereby contributing to enhanced stool volume and an increase in peristaltic contractions to move

it out of the colon. These actions stem from two events: An increased production of acetate,

proprionate and butyric short chain fatty acids to promote fermentation, or digestion; and the

successful conversion of glycosides into a powerful purgative agent known as rheinanthrone.



If you have fewer than three bowel movements per week or your stools are harder than usual,

you may have constipation, according to the University of Maryland Medical Center. Stress, chronic

disease, or certain medications may cause constipation. Inadequate fiber or fluid intake and lack

of physical activity can also contribute. If constipation lasts for more than a few days, talk to your

doctor about what might be causing it.



Senna and Constipation
Senna may relieve constipation by stimulating the muscles of the colon to push fecal matter

through more quickly. It may also help your colon absorb water to soften stool. You may expect a

bowel movement within six to 10 hours of taking senna, according to the National Cancer Society.

Active compounds in the senna plant, called sennosides, may be responsible for its laxative effect.



Side Effects
Senna can cause diarrhea, which may lead to dehydration and electrolyte imbalance. You may

experience nausea or vomiting, although these issues are less common. Some people may be allergic

to senna leaves. The color of your urine may change while you are taking senna laxatives, but should

go back to normal when you stop. Avoid using senna for long periods of time, as chronic use may

impair the normal function of your colon, cautions the American Cancer Society. Consult with your

doctor before using senna if you are pregnant or nursing.



Before you consider using senna for constipation, make sure you are consuming enough fiber and

water every day. Aim for a total dietary fiber intake of at least 25 grams daily for women and 38

grams per day for men, advises the US Department of Agriculture. Increase your fiber intake

gradually and drink at least eight glasses of water daily to avoid potential side effects of fiber, such

as gas and bloating. The more fiber you consume, the more fluids you should drink, says the

Academy of Nutrition and Dietetics.
