Epimedium Side Effects: Horny Goat Weed Safety Notes
Epimedium side effects are poorly studied in people. A review of mostly lab and animal research says crude extracts show potential liver toxicity and calls for more safety work. Epimedium, also sold as horny goat weed, is listed in Quietum Plus without an amount, so ask your doctor or pharmacist before you order.

What are the side effects of epimedium?
The main safety flag for epimedium is possible liver toxicity from crude extracts. A review of Epimedium koreanum describes this as a concern and says more toxicology work is needed (Qian et al., Epimedium Review).
That review covers laboratory and animal studies, not human trials. It lists more than 379 compounds found in the plant, which shows how complex an extract can be. Complex extracts vary, and so does what ends up in a capsule.
So we cannot give a list of side effects with rates. We can say what is known, and what is not.

What is horny goat weed and who should ask first?
Horny goat weed is a common name for epimedium, a plant used in traditional medicine as a kidney tonic and for impotence (Qian et al., Epimedium Review). Today it is sold mostly for libido.
Anyone with liver disease, anyone who takes medicine that the liver processes, and anyone who is pregnant should ask a doctor before using it. Our sources do not test those groups.
Products sold for sexual enhancement have also been found tainted with hidden drugs, which is why look-alike listings are a risk (FDA, Sexual Enhancement Product Notifications). Buy only through the official route.
- Yellow skin or eyes, dark urine or strong itching need prompt medical care.
- Keep taking prescribed medicine and ask your prescriber about the mix.
- Tell every provider about every supplement (NCCIH, Using Dietary Supplements Wisely).
Is epimedium used for tinnitus?
No source we cite links epimedium to tinnitus or hearing. Its research is about reproductive, heart and nerve effects in the lab.
The NIDCD says no vitamin, herb or supplement advertised for tinnitus has been shown to work (NIDCD, Tinnitus). Ringing deserves its own check. Sudden hearing loss in one ear needs same-day care, and ringing that beats with your pulse, follows a head injury, or comes with dizziness, weakness or a drooping face needs a doctor. Face weakness is an emergency.
A hearing exam, then talk therapy or a hearing aid check if they fit your results.

See packsWhat should you know about epimedium in Quietum Plus?
Epimedium shares the second sales-page tile with Tribulus terrestris. Quietum Plus is a capsule supplement, 60 per bottle, and the images we reviewed print no amounts, serving or warnings.
Because the epimedium amount is missing, nobody can compare it with any study. The bottle front lists Clear Mind, Memory & Focus and Mood Support, not hearing. Read the epimedium and tribulus page, then supplements and medicines for questions to bring.
Packs cost $79, $69 or $49 a bottle, and a 60-day money-back guarantee covers every pack. Follow your bottle's label.

01FAQ
Epimedium questions
Is epimedium the same as horny goat weed?
Yes. Horny goat weed is a common name for plants in the Epimedium family. Labels may list either name, or the active compound icariin. Check the full ingredient list on your bottle, since several names can describe the same plant.
Can epimedium harm the liver?
Possibly. A review says crude extracts show potential hepatotoxicity, based on lab and animal research. We found no human trial that measures the risk. If you have liver disease or take liver-processed medicine, ask your doctor before use.
Is there a safe amount of epimedium?
We cannot give one. The sources we cite set no safe amount, and Quietum Plus prints none. Follow your bottle's label, and ask your doctor or pharmacist if you take medicine or have a medical condition.
