Hyssop

Supplement Forms/Alternate Names:

Hyssopus officinalis

Introduction

Hyssop is a flowering plant that grows in North America and Europe. Its flowers and seeds have been used to ease sore throat and cough. It can be taken as a pill, powder, or extract. Hyssop can also be made into a tea or used as an essential oil.

Dosages

There are no advised doses for hyssop.

What Research Shows

There is not enough data to support that hyssop is helpful in treating health problems. We will review future studies as they are published.

Editorial process and description of evidence categories can be found at EBSCO NAT Editorial Process.

Safety Notes

It is likely safe for most adults to take a small amount of hyssop and use it on the skin for a short time, but stomach upset, anxiety, and tremors are possible. Not enough studies have been done to say whether it is safe to use for a long period. Hyssop should not be used by children or by women during pregnancy and breastfeeding.

Interactions

Talk to your doctor about any supplements or therapy you would like to use. Some can interfere with treatment or make conditions worse, such as:

  • Hyssop may worsen symptoms in children with seizure disorders.1
