What is the active compound in black cohosh that is used for menopausal symptoms?

The active compound in black cohosh that is most commonly recognized for its therapeutic effects on menopausal symptoms is indeed triterpene glycosides. These compounds are a class of chemical compounds that play a significant role in the plant’s pharmacological activity. Triterpene glycosides in black cohosh are believed to act on hormone receptors, which can help alleviate symptoms such as hot flashes and mood swings associated with menopause.

The structure of triterpene glycosides allows them to engage in various biological interactions, contributing to their effectiveness. This specific class of compounds has been studied for its potential to mimic estrogen activity, which is particularly valuable for women experiencing menopause when natural estrogen levels decline.

In contrast, the other options—alkaloids, flavonoids, and carotenoids—represent different classes of compounds that may serve various roles in plants but are not primarily associated with the effects attributed to black cohosh in the context of menopausal symptom relief. Each of these groups has distinct properties and potential health benefits, yet they do not relate directly to the active action for which black cohosh is noted in this particular application.
