What is Forskolin used for?

Traditional/Ethnobotanical uses

This species and other related species were used in Ayurvedic medicine under the name pashanabhedi for heart and lung diseases, intestinal spasms, insomnia, and convulsions. It was studied for cardiovascular activity in 1974 by scientists from Hoechst India and the Central Drug Research Institute of India in screening programs that examined medicinal plants.

Cardiovascular effects

Forskolin has been shown to dilate the blood vessels, decreasing blood pressure, increasing the contractility of the heart, and inhibiting platelet aggregation in patients. Because of its multiple sites of action, it should be used with caution. Research reveals no clinical data regarding the use of forskolin for antithrombotic effects. Forskolin has shown positive effects in human heart tissues. More clinical studies are needed.

Asthma

Forskolin has been shown to relax contracted airways in humans. A small human study found that inhaled forskolin powder formulations were capable of causing bronchodilation in asthma patients. Further clinical study is necessary.

What is the dosage of Forskolin?

Typical dosage is 100 to 300 mg/day of an extract containing 10% to 20% forskolin.

Is Forskolin safe?
