Interaction report

Safflower and Neomycin, Polymyxin B, Gramicidin

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 Neomycin, Polymyxin B, Gramicidin and Safflower 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.

What to actually watch for

What Safflower Itself Has Been Linked To

This is not an interaction — nothing below involves Neomycin, Polymyxin B, Gramicidin. It is the side-effect record for Safflower on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Safflower, this list is the first place to look.

  • Weight loss Additional detail

    “Orally, safflower oil has been associated with liver failure. There are at least 7 case reports of acute liver failure requiring liver transplant that are probably associated with over-use of safflower oil, usually for weight loss purposes. However, it is not clear what dose or duration of safflower use led to liver failure in these cases.”

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

About Safflower

What is Safflower?

Safflower
  • Heart and cholesterol support
  • Skin moisturizing
  • Menstrual cramps
  • Mild constipation
  • Weight management (oil)

Safflower is a thistle-like plant used mainly for its seed oil (a common cooking oil) and its colorful flowers. Safflower oil is a reasonable source of unsaturated fats, but strong proof that supplements treat specific diseases is limited. The flower extracts have much weaker evidence and should be used with caution, especially during pregnancy.

Carthamus tinctorius · Asteraceae · Flowers (petals), seeds, and seed oil · Cooking oil, capsules (oil or CLA), tea, dried flowers, topical oil

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

Safflower: dosing

There is no official standardized dose for safflower as a medicine. Products vary widely, from cooking oil to capsules of oil, CLA, or dried flower extract, and each will have its own label directions.The best advice is to follow the directions on the product label and not exceed the recommended amount.
