Black Hoof Mushroom and Erythromycin

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Erythromycin and Black Hoof Mushroom in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

How we checked

Why No Interaction Is Listed for Erythromycin

Interactions in our licensed database are recorded against drug classes, not just single drug names. Erythromycin is filed under 9 classifications — including macrolide antibiotics, cytochrome p450 1a2 (cyp1a2) inhibitors, qt interval-prolonging drugs. Black Hoof Mushroom has documented interactions with 3 drug classes — the most serious being cytochrome p450 1a2 (cyp1a2) substrates (moderate), cytochrome p450 2e1 (cyp2e1) substrates (moderate) and immunosuppressants (moderate) — and none of Erythromycin’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

From our pharmacist’s overview on the Erythromycin page

“Erythromycin calls for more supplement caution than most antibiotics, and the reason is one liver enzyme, CYP3A4. Erythromycin both blocks that enzyme and is broken down by it, so grapefruit can push erythromycin levels up while St.”

About Black Hoof Mushroom

What is Black Hoof Mushroom?

Black Hoof Mushroom
  • Immune system support
  • Antioxidant support
  • General wellness
  • Traditional cancer-supportive use
  • Inflammation

Black Hoof Mushroom (Phellinus linteus) is a medicinal mushroom long used in East Asian traditional medicine, mainly for immune support. Most of the supporting evidence comes from laboratory and animal studies, and high-quality human research is limited. Talk to your pharmacist or doctor before using it, especially if you have a health condition or take other medicines.

An interaction check asks whether these two react with each other — it does not ask whether Black Hoof Mushroom is a good idea for someone in your situation. Here is what our Black Hoof Mushroom record says about it on its own.
