In the scientific community, it is known as Senna alexandrina or Cassia angustifolia. It is a plant that can reach a height of 1.5 m. The fruit, meanwhile, has the appearance of a flattened pod and contains 6 to 8 seeds which are poisonous. This plant also contains many active ingredients. Mention may in particular be made of mucilages, flavonoids, sennosides, anthraquinones and naphthalene glycosides. These components are primarily responsible for the medicinal properties of senna.
Uses in natural medicine
Senna is reputed to be a powerful laxative. For this purpose, it is used to stimulate intestinal transit and to facilitate the progression of the food bolus. It is particularly indicated in case of transient constipation. Moreover, associated with a diet rich in fiber, it is effective in case of intestinal laziness.
In addition, it promotes the appearance of loose stools. It is therefore prescribed in cases of anal fissures and hemorrhoids.
Taking this plant is also recommended before proceeding to a colonoscopy or radiology. Its purifying property allows, in fact, to purge the intestines. Note that this is one of the conditions required to identify the exact cause of a condition.
