Alder Buckthorn Overview

Alder Buckthorn Alder buckthorn (Rhamnus frangula) is an invasive shrub native to Europe and North America. Its bark has been traditionally used in medicine due to its cathartic effects in the large intestine, attributed to its anthraglycoside content. It is generally used to help alleviate constipation. However, chronic use of alder buckthorn has been linked to gastrointestinal epithelial cell damage, pigmentation of the colonic mucosa (pseudomelanosis coli), and a potential risk of colorectal cancer. If used as a dietary supplement, the duration of use for alder buckthorn should be limited to no more than a few days altogether, due to its potential adverse effects on gastrointestinal health with prolonged use. In 1993, the FDA removed its Generally Recognized As Safe (GRAS) status due to insufficient safety data, particularly regarding prolonged use of its anthraquinone laxatives, reinforcing the need for caution in its medicinal use.

Simvastatin Overview

  • Simvastatin is used together with diet, weight-loss, and exercise to reduce the risk of heart attack and stroke and to decrease the chance that heart surgery will be needed in people who have heart disease or who are at risk of developing heart disease. Simvastatin is also used to decrease the amount of fatty substances such as low-density lipoprotein (LDL) cholesterol (''bad cholesterol'') and triglycerides in the blood and to increase the amount of high-density lipoprotein (HDL) cholesterol (''good cholesterol'') in the blood. Simvastatin may also be used to decrease the amount of cholesterol and other fatty substances in the blood in children and teenagers 10 to 17 years of age who have familial heterozygous hypercholesterolemia (an inherited condition in which cholesterol cannot be removed from the body normally). Simvastatin is in a class of medications called HMG-CoA reductase inhibitors (statins). It works by slowing the production of cholesterol in the body to decrease the amount of cholesterol that may build up on the walls of the arteries and block blood flow to the heart, brain, and other parts of the body.

  • Accumulation of cholesterol and fats along the walls of your arteries (a process known as atherosclerosis) decreases blood flow and, therefore, the oxygen supply to your heart, brain, and other parts of your body. Lowering your blood level of cholesterol and fats with simvastatin has been shown to prevent heart disease, angina (chest pain), strokes, and heart attacks.
