Interaction Details
There were no interactions found between Raloxifene and Gymnema. This does not mean the potential for an interaction does not exist, however. There is often a lack of studies and data surrounding traditional medicine, especially concerning drug interactions, so it is important to always consult your provider before making any changes to your medication regimen.
Gymnema Overview
Gymnema (Gymnema sylvestre) is a plant species native to India and Africa that has been used traditionally in Ayurvedic medicine for centuries to treat a range of conditions, including diabetes, obesity, and digestive problems.
Gymnema is thought to work by inhibiting the absorption of sugar in the intestines and by increasing the production of insulin in the pancreas. If applied topically to the tongue, it reduces the sweetness and bitter sensation of foods, which may deter excess sugar intake (the plant is sometimes referred to informally as 'the sugar destroyer').
One of the most popular natural medicines utilized for dietary supplements, an extract of the leaf (Gymnema leaf extract) is the most often standardized for use, although the root can be used as well.
Raloxifene Overview
-
Raloxifene is used to prevent and treat osteoporosis (condition in which the bones become thin and weak and break easily) in postmenopausal (women who have experienced a change of life; end of menstrual periods) women. Raloxifene is also used to decrease the risk of developing invasive breast cancer (breast cancer that has spread outside of the milk ducts or lobules into the surrounding breast tissue) in postmenopausal women who are at high risk of developing this type of cancer or who have osteoporosis. Raloxifene cannot be used to treat invasive breast cancer or to prevent invasive breast cancer from coming back in women who have already had the condition. Raloxifene also cannot be used to decrease the risk of developing noninvasive breast cancer. Raloxifene should not be used in women who have not yet experienced menopause. Raloxifene is in a class of medications called selective estrogen receptor modulators (SERMs). Raloxifene prevents and treats osteoporosis by mimicking the effects of estrogen (a female hormone produced by the body) to increase the density (thickness) of bone. Raloxifene decreases the risk of developing invasive breast cancer by blocking the effects of estrogen on breast tissue. This may stop the development of tumors that need estrogen to grow.
