Common effects
What are the common side effects of horny goat weed?
Minor stomach upset and nausea are the common ones. LiverTox calls the plant generally well tolerated, with rare rash and allergic reactions, and rates liver injury as unlikely (LiverTox, Horny goat weed).
MSK adds more: sweating or feeling hot, increased energy, mood changes and a rapid irregular heartbeat (MSK, Epimedium (horny goat weed)). It lists a case report of hypomania and a case of tachyarrhythmia in a man with heart failure. These are reports, not rates.
- Mild: stomach upset, nausea, sweating.
- Rare: rash, allergic reaction, mood changes.
- Serious: rapid irregular heartbeat.

Is horny goat weed safe for the heart?
Not for everyone. MSK says not to take it if you have heart disease, because of reports of a rapid irregular heartbeat (MSK, Epimedium (horny goat weed)).
The same page names a case in a man with heart failure. We found no heart-safety trial of horny goat weed. If you have a heart condition, high blood pressure or a pacemaker, ask your cardiologist before any supplement.

Should you ask a doctor before using horny goat weed?

FAQ
HoneyBoost questions people ask
Can horny goat weed cause a fast heartbeat?
MSK lists a rapid irregular heartbeat as a possible effect and says to avoid the plant with heart disease. Call 911 for chest pain, and see a clinician if your heart races.
Is horny goat weed bad for the liver?
LiverTox rates liver injury from horny goat weed as unlikely (score E) and calls it generally well tolerated. That is no promise for every product, so report yellow skin or dark urine.
Does horny goat weed work for erections?
MSK cites no human trial of sexual function, and LiverTox says rigorous trials are lacking. The label makes no treatment claim in words, and ED deserves a doctor's visit.
