Interaction report

Pinellia Ternata and Colistin, Neomycin, Hydrocortisone

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 Colistin, Neomycin, Hydrocortisone 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.

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.
