Guarana Overview

Guarana Guarana (Paullinia cupana) is a plant native to the Amazon rainforest in South America. The seeds of the guarana plant are used in traditional medicine and as a dietary supplement. Guarana is often marketed as a natural stimulant and is claimed to improve physical performance, increase energy and alertness, and reduce fatigue. It is sometimes added to energy drinks, weight loss supplements, and other products. Guarana seeds typically contain around 3-6% caffeine, although some extracts may contain far more. Guarana, when used in dietary supplements, is often standardized for its caffeine and tannin content.

Tretinoin Overview

  • Tretinoin is used to treat acute promyelocytic leukemia (APL; a type of cancer in which there are too many immature blood cells in the blood and bone marrow) in people who have not been helped by other types of chemotherapy or whose condition has improved but then worsened following treatment with other types of chemotherapy. Tretinoin is used to produce remission (a decrease or disappearance of signs and symptoms of cancer) of APL, but other medications must be used after treatment with tretinoin to prevent the cancer from returning. Tretinoin is in a class of medications called retinoids. It works by slowing or stopping the growth of cancer cells by causing immature blood cells to develop into normal blood cells.
