Thyme, Ivy and Other Herbs Traditionally Used for Mucus

Long before modern medicine, people turned to plants when their chest felt heavy. Several of those herbs are still widely used today. Here's what we know about the best-known ones.

Mullein

A tall, fuzzy-leaved plant with a long history as a chest-and-throat herb across several cultures. Its saponins are often cited as the reason for its traditional use. There are no placebo-controlled human trials for cough or mucus yet.

Thyme

Common kitchen thyme has been used for coughs for centuries. It's also one of the better-studied herbs in this group: combinations of thyme and ivy leaf have been tested in clinical trials for acute bronchitis cough in Europe, with some positive results.

Ivy leaf

Ivy leaf extract is widely used in European cough syrups. Several studies suggest it may help with cough, though study quality varies.

Licorice root

A traditional throat soother. Be cautious: large amounts over time can raise blood pressure and lower potassium, so it's not ideal for everyone.

Ginger

Better known for nausea, ginger has interesting lab research showing its compounds relax airway muscle tissue — though that hasn't yet been shown in people who swallow it.
