Is Mullein Safe? What to Know Before You Try It

Mullein is one of the most popular herbs for respiratory wellness. It has a long history of use and is generally considered gentle, but it's still worth knowing the facts before you try it.

Is mullein generally safe?

Mullein leaf is generally well tolerated by most adults when taken by mouth in typical amounts. Serious side effects appear to be rare. That said, it hasn't been studied as thoroughly as many medicines, so caution is sensible.

Possible side effects

• Throat irritation — from the tiny hairs on mullein leaves, if a tea isn't properly strained.
• Skin irritation — some people react to handling the fresh plant.
• Allergic reactions — possible, as with any plant.

Who should avoid it or check first

• People who are pregnant or breastfeeding — there isn't enough safety data.
• Children — speak to a paediatrician first.
• Anyone taking regular medication — check with a pharmacist.
• Anyone with a diagnosed lung condition.

Choosing a quality product

Look for a product that lists every ingredient by name, is made in a GMP-certified facility, and doesn't hide amounts in a proprietary blend. Liquid extracts like BreathiZen® avoid the leaf-hair problem entirely.
