Scientific Summary
Coleus forskohlii is a tropical perennial herb whose root contains the active compound forskolin. It is commonly used to support cardiovascular health, lower blood pressure, and relieve smooth‑muscle spasms, and it is also marketed as a supplement for weight loss and endurance. Because forskolin can lower blood pressure and interfere with certain medications, people taking antihypertensives, blood thinners, or pregnant or nursing women should use caution and consult a healthcare professional before using it.
