Senna Overview

Senna Senna is a plant that belongs to the legume family. It is native to tropical and subtropical regions of the world, and it is widely cultivated for its medicinal properties. Senna contains compounds called sennosides, which are found in the leaves, stem, and pods of the plant. These compounds stimulate the muscles in the walls of the intestine, causing the bowel to contract and move waste through the intestines. Senna is used as a natural laxative to help relieve constipation. It is often marketed as a 'natural vegetable laxative'. It is available in a number of forms, including tablets, capsules, and a liquid extract. Although it can cause dependence with long-term use (i.e., the body becomes dependent on it for regular bowel movements), when compared to other stimulant laxatives, like bisacodyl, it is considered safer in that regard.

Donepezil Overview

  • Donepezil is used to treat dementia (a brain disorder that affects the ability to remember, think clearly, communicate, and perform daily activities and may cause changes in mood and personality) in people who have Alzheimer's disease (AD; a brain disease that slowly destroys the memory and the ability to think, learn, communicate and handle daily activities). Donepezil is in a class of medications called cholinesterase inhibitors. It improves mental function (such as memory, attention, the ability to interact with others, speak, think clearly, and perform regular daily activities) by increasing the amount of a certain naturally occurring substance in the brain. Donepezil may improve the ability to think and remember or slow the loss of these abilities in people who have AD. However, donepezil will not cure AD or prevent the loss of mental abilities at some time in the future.
