Vietnamese Coriander and Estradiol, Norgestimate

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 Estradiol, Norgestimate and Vietnamese Coriander 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.

Worth understanding: our licensed dataset holds no drug-interaction record for Vietnamese Coriander at all — not against Estradiol, Norgestimate, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

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 Vietnamese Coriander

What is Vietnamese Coriander?

  • Flavoring food
  • Digestive upset
  • Antimicrobial uses
  • Reducing sexual desire (traditional)
  • Skin and wound care (traditional)

Vietnamese coriander (rau ram) is a fragrant Southeast Asian culinary herb traditionally used for digestion and as an antimicrobial. There is very little human research to support its medicinal uses, so it is best thought of as a flavorful food rather than a proven remedy. Pregnant and breastfeeding people should avoid medicinal amounts, and anyone considering it as a supplement should check with a pharmacist or doctor.

Persicaria odorata · Polygonaceae · Leaves and stems · Fresh leaves (culinary herb), dried leaves, tea, essential oil

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

Vietnamese Coriander: dosing

There is no established or standardized medicinal dose for Vietnamese coriander. It is most often used simply as a fresh culinary herb, added to dishes to taste.If you choose to use a tea or supplement product, follow the directions on the label and do not exceed the recommended amount.
