Cudweed and Butenafine

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 Butenafine and Cudweed 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.

Cudweed safety at a glance

Cudweed overall Not established Limited modern safety data exist, so use with caution and talk to a healthcare provider first.
Pregnancy Avoid Not enough safety information is available, so avoid use during pregnancy.
Breastfeeding Avoid There is no reliable safety data, so avoid use while breastfeeding.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Butenafine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Butenafine is filed under 2 classifications — antifungals, oral drugs. Cudweed has documented interactions with 1 drug class — the most serious being antidiabetes drugs (moderate) — and none of Butenafine’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 Butenafine page

“Butenafine (Mentax), an antifungal cream for athlete's foot, jock itch, and ringworm, carries a supplement list that deserves real vigilance, and most of that vigilance points at one entry. Activated charcoal, the only major-rated interaction of the 20 on file, can reduce the body's exposure to many drugs regardless of how they were gi…”

About Cudweed

What is Cudweed?

  • Mouth and throat irritation
  • Digestive upset
  • Mild high blood pressure (traditional)
  • Minor wounds and skin irritation
  • Coughs and respiratory complaints

Cudweed is a small, woolly-leaved plant used in traditional herbal medicine, mainly as a tea or gargle for sore throats, digestive upset, and minor skin problems. There is very little modern scientific evidence to confirm that it works for any condition, and safety data are limited, so it is best used cautiously and avoided in pregnancy and breastfeeding.

Gnaphalium uliginosum · Asteraceae · Aerial parts (flowering tops, leaves, and stems) · Tea (infusion), tincture, dried herb

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

Cudweed: dosing

There is no established or standardized dose for cudweed. It has not been studied enough to know a safe and effective amount, and traditional preparations vary.If you choose to use a commercial product, follow the directions on the label and do not exceed the recommended amount.

From our Cudweed monograph — the full record covers uses, side effects and every documented interaction.

About Butenafine

What Is Butenafine Used For?

Brand name: Mentax

Butenafine treats common fungal skin infections. Products containing butenafine — including Athletes Foot, Athletes Foot Ultra, Butenafine Hydrochloride, Butenafine Hydrochloride 1%, Jock Itch, and Jock Itch Cream — cure most cases of athlete's foot (between the toes), jock itch, and ringworm. They also relieve the itching, burning, cracking, and scaling that come with these infections.

For athlete's foot, these products work between the toes. Effectiveness on the bottom or sides of the foot is not established. Jock Itch and Jock Itch Cream are specifically indicated for jock itch and its associated symptoms.
