Hyssop and Amlodipine Besylate

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 Amlodipine Besylate and Hyssop 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 Hyssop at all — not against Amlodipine Besylate, 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 Hyssop

What is Hyssop?

Hyssop
  • Coughs and colds
  • Sore throat and congestion
  • Digestive upset and gas
  • Aromatherapy
  • Insect repellent

Hyssop is a Mediterranean mint-family herb traditionally used for coughs, colds, and digestive complaints, but solid human evidence for these uses is lacking. The dried herb in tea is generally considered low-risk for most adults, but the concentrated essential oil can cause seizures and should not be used internally. Avoid hyssop products during pregnancy and breastfeeding, and check with your pharmacist or doctor before using it.

Hyssopus officinalis · Lamiaceae · Above-ground parts (leaves, flowers, and stems) and the essential oil · Tea, capsules, tablets, tincture, essential oil

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

Hyssop: dosing

There is no well-established standardized dose for hyssop. Traditional use most often involves a tea made from a small amount of the dried herb steeped in hot water. Capsule and tablet products vary widely in strength.If you use a commercial product, follow the directions on the label and do not exceed them. Do not take the essential oil internally.
