Diseases of the heart and blood vessels (cardiovascular disease): Due to the levodopa (L-dopa) in cowhage, it should be avoided or used cautiously in people with cardiovascular disease. L-dopa can frequently cause low blood pressure on standing (orthostatic hypotension), dizziness, and fainting. Much less frequently, L-dopa can also cause pounding or irregular heartbeat.

Skin cancer called melanoma: The body can use the levodopa (L-dopa) in cowhage to make to the skin pigment called melanin. There is some concern that this extra melanin might make melanoma worse. Don't use cowhage if you have a history of melanoma or a suspicious changes in the skin.
Stomach or intestinal ulcers (peptic ulcer disease): There have been reports that levodopa (L-dopa) can cause gastrointestinal (GI) bleeding in people with ulcers. Since cowhage contains L-dopa, there is some concern that it might cause gastrointestinal (GI) bleeding in patients with ulcers. However, this problem has not yet been reported with cowhage.
Mental illness: Due to the levodopa (L-dopa) content, cowhage might make mental illness disease worse.
Surgery: Since cowhage might affect blood sugar levels, there is some concern that it might interfere with blood sugar control during and after surgery. Stop taking cowhage at least 2 weeks before a scheduled surgery.
