Only one source links horny goat weed to Soda Horse Peak: an eBay listing with “Purvia” in its brand field. It names the herb among eleven others and prints no amounts.

The look-alike sites do not list it, and no Supplement Facts panel is published. So whether a gummy holds any horny goat weed is not confirmed. Our ingredients page compares every claimed list.

Background

What is horny goat weed?

Horny goat weed is the common name for Epimedium, a leafy plant grown in parts of Asia. Its leaves have long been used in traditional Chinese practice. Today it is sold to men for sex drive and erections.

The compound researchers study most is icariin. Labels seldom say how much icariin a product contains, which makes products hard to compare.

Research

What does research say about horny goat weed?

The human evidence is preliminary, according to WebMD (WebMD, Horny goat weed). That means early studies and no firm proof of a benefit for men.

Lab findings do not always carry over to people. Until larger human trials exist, treat any ED promise with care. The tongkat ali page shows the same pattern for another herb on the eBay list.

Blood pressure

Does horny goat weed affect blood pressure?

It may lower it. WebMD lists low blood pressure as a concern (WebMD, Horny goat weed). For a healthy man this may pass unnoticed. For a man already on pressure-lowering drugs, it can stack up.

ED pills and nitrates can also lower blood pressure. That is why the nitroglycerin warning below matters so much.

Blood pressure and heart concerns for horny goat weed, based on WebMD, checked October 12, 2026.
RiskWhat you might noticeWhat to doSource
Low blood pressureDizziness, lightheadedness, faintingSit down; call your doctor; call 911 if you faint(WebMD, Horny goat weed)
Irregular heartbeatFluttering, skipped beats, a racing pulseStop and call your doctor the same day(WebMD, Horny goat weed)
Mix with nitroglycerinSevere drop in blood pressureDo not combine without your doctor(WebMD, Horny goat weed)
Mix with ED pills or blood pressure drugsLarger drop in pressureAsk your doctor before you start(WebMD, Horny goat weed)

Low pressure often shows up when you stand fast. You may feel lightheaded, see spots or need to grab something for balance. If that happens, sit or lie down and drink some water. If it keeps happening, stop the product and call your doctor. A home blood pressure cuff can help you spot a pattern to share at your visit.

Heart rhythm

Can horny goat weed cause an irregular heartbeat?

Yes, that is one of the listed concerns (WebMD, Horny goat weed). You might feel a flutter, a skipped beat or a pounding pulse. Men with a known rhythm problem, such as atrial fibrillation, should not try it without their doctor.

No amount is published for this gummy, so there is no way to judge the dose. That alone is a reason to start with your doctor.

When to get help now

Chest pain, fainting or a racing heartbeat that will not settle: call 911. An erection lasting more than 4 hours also needs emergency care.

Nitrates

Why is horny goat weed dangerous with nitroglycerin?

Nitroglycerin lowers blood pressure, and horny goat weed may lower it too. Together, the drop can be dangerous, and WebMD warns against the mix (WebMD, Horny goat weed).

The same risk applies to hidden ED drugs. The FDA has found undeclared sildenafil and tadalafil in some sexual enhancement products (FDA, Hidden drugs in sexual enhancement products). If you carry nitroglycerin for chest pain, talk to your cardiologist before any sexual health product.

Claimed together

Which other herbs share the eBay list?

The same listing names ten more items. Each brings its own notes, and several affect the same body systems.

Ashwagandha, shilajit, turkesterone, fadogia, saw palmetto and apple cider vinegar complete the list. None of these is confirmed on a label either.

Doctor visit

What should you tell your doctor?

A short, plain list makes the visit quick. Doctors talk about erection problems every day, so there is no need to feel awkward.

Honest note

Honest note: what is known and what is not

We cannot say whether Soda Horse Peak contains horny goat weed, or how much. No panel has been published, and no trial of the gummy exists. The herb's own evidence is preliminary.

What is clear is the value of a checkup. ED can be an early warning sign of heart disease (Mayo Clinic, ED and heart disease). Your doctor can check your heart and talk through proven treatments. Sleep, activity, less alcohol and no smoking help too.
