Forskolin is a chemical in the roots of the Plectranthus barbatus plant that is used to treat heart disorders, states WebMD. In a January 2014 episode of his show, Dr. Oz called forskolin a "miracle flower" and "lightning in a bottle," according to Forbes.
Forskolin improves cardiovascular function by widening the blood vessels and producing a more powerful heartbeat, notes WebMD. Health care providers sometimes administer it intravenously for patients with heart failure. When taken by mouth, forskolin helps treat allergies, obesity, irritable bowel syndrome, painful periods and urinary tract infections. Forskolin drops are used to treat eyes afflicted with glaucoma, and some people inhale a powdered version of the chemical to help treat asthma.
