Ayahuasca Overview
Ayahuasca is a psychoactive drink made from the Ayahuasca vine (Banisteriopsis caapi) and other plants, such as Psychotria viridis. Ayahuasca contains beta-carboline alkaloids and the hallucinogen dimethyltryptamine (DMT). It is used for ceremonial and medicinal purposes and is known for its powerful hallucinogenic effects. Although ayahuasca has been used traditionally in some cultures, it is not legal in many areas of the world and has been reported to cause serious life-threatening adverse reactions. Its use is not recommended due to safety concerns.
Alpelisib Overview
-
Alpelisib (Piqray) is used in combination with fulvestrant (Faslodex) to treat a certain type of breast cancer that has spread to nearby tissues or other parts of the body in women who have already gone through menopause (''change of life,'' end of menstrual periods) or in men, whose cancer got worse during or after certain other treatments. Alpelisib (Vijoice) is used to treat adults and children 2 years of age or older who have certain types of PIK3CA Related Overgrowth Spectrum (PROS; a genetic condition that causes overgrowth and abnormalities in certain body tissues). Alpelisib is in a class of medications called kinase inhibitors. It works to treat cancer by blocking the signals that cause cancer cells to multiply, which helps to stop the spread of cancer cells. It works to treast PROS by blocking the signals that cause overgrowth and abnormalities in certain body tissues, which reduces the size of the overgrowths and improves symptoms.
