Interaction report

Cnidium and Methyclothiazide, Pargyline

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 Methyclothiazide, Pargyline and Cnidium 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 Methyclothiazide, Pargyline

Interactions in our licensed database are recorded against drug classes, not just single drug names. Methyclothiazide, Pargyline is filed under 6 classifications — including thiazide diuretics, diuretic drugs, antihypertensive drugs. Cnidium has documented interactions with 2 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate) and cns depressants (moderate) — and none of Methyclothiazide, Pargyline’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.

About Cnidium

What is Cnidium?

Cnidium
  • Skin conditions and itching
  • Erectile dysfunction and low libido
  • Eczema and dermatitis
  • Antifungal or antimicrobial washes
  • Athletic performance
  • General antioxidant support

Cnidium is the dried fruit of an Asian plant long used in traditional Chinese medicine, mostly for skin problems and sexual health. Modern human evidence for these uses is very limited, with most research coming from laboratory and animal studies. Talk with your pharmacist or doctor before using it, and avoid it during pregnancy and breastfeeding.

Cnidium monnieri · Apiaceae (Umbelliferae) · Dried ripe fruit (seeds); sometimes the rhizome · Capsules, powdered extract, tinctures, topical creams and ointments, and as an ingredient in traditional Chinese herbal formulas

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

Cnidium: dosing
