Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first.

Pinellia Ternata and Mavacamten

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 Mavacamten and Pinellia Ternata 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.

Pinellia Ternata safety at a glance

Pinellia Ternata overall Use caution Raw Pinellia is toxic and irritating; only properly processed material used under professional guidance should be considered.
Pregnancy Avoid Traditionally cautioned against and lacking safety data, so it should be avoided in pregnancy.
Breastfeeding Avoid There is not enough safety information, 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 Mavacamten

Interactions in our licensed database are recorded against drug classes, not just single drug names. Mavacamten is filed under 3 classifications — cytochrome p450 2c19 (cyp2c19) substrates, cytochrome p450 3a4 (cyp3a4) substrates, oral drugs. Pinellia Ternata has documented interactions with 3 drug classes — the most serious being barbiturates (moderate), benzodiazepines (moderate) and cns depressants (moderate) — and none of Mavacamten’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.

What to actually watch for

What Pinellia Ternata Itself Has Been Linked To

This is not an interaction — nothing below involves Mavacamten. It is the side-effect record for Pinellia Ternata on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Pinellia Ternata, this list is the first place to look. 3 entries are worth acting on rather than waiting out — marked below.

  • A heart attack / Raised blood pressure Worth acting on Additional detail

Everything above comes from the Natural Medicines adverse-effect record for Pinellia Ternata — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Mavacamten’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Mavacamten column appears here.

Everything else you take

See Every Supplement That Interacts With Mavacamten

This page covers Pinellia Ternata only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Mavacamten page lists 143 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Grapefruit (major), St. John's Wort (major), Acacia Rigidula (moderate) and Adrafinil (moderate).

By severity: 3 major · 100 moderate · 40 minor.

From our pharmacist’s overview on the Mavacamten page

“Grapefruit is the first thing I would set aside for anyone taking mavacamten (Camzyos), the medicine for obstructive hypertrophic cardiomyopathy. It blocks CYP3A4, the liver enzyme that clears mavacamten, and too much of this drug can weaken the heart's pumping strength, the very problem careful dosing exists to prevent.”

About Pinellia Ternata

What is Pinellia Ternata?

  • Nausea and vomiting
  • Cough with phlegm
  • Morning sickness (traditional use)
  • Digestive upset and bloating
  • Throat discomfort

Pinellia ternata is a tuber used in traditional Chinese medicine, most often for nausea, vomiting, and phlegmy coughs, and almost always as part of multi-herb formulas. The raw plant is toxic and must be specially processed before use, so it should only be used under qualified guidance. Solid human evidence is limited, and it should be avoided in pregnancy and breastfeeding.

Pinellia ternata · Araceae · Dried tuber (rhizome), usually processed before use · Dried processed tuber, powder, granules, decoctions (teas), and part of multi-herb traditional formulas

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

Pinellia Ternata: dosing

There is no well-established standardized dose of Pinellia ternata for supplement users. In traditional Chinese medicine it is given as processed tuber within specific multi-herb formulas, with the amount and preparation chosen by a trained practitioner.Because the raw herb is toxic and product quality varies, you should not try to dose this herb on your own. If you use a product, follow the label exactly and ideally work with a qualified practitioner.

About Mavacamten

Camzyos (mavacamten) is approved for adults with symptomatic obstructive hypertrophic cardiomyopathy (HCM) — specifically those with New York Heart Association (NYHA) class II or III symptoms, meaning the condition noticeably limits their daily activity. It is used to improve exercise capacity and relieve symptoms like shortness of breath and chest discomfort caused by the obstruction.
