Rosemary

Also known as Salvia rosmarinus

Rosemary contains rosmarinic acid, an antioxidant and anti-inflammatory compound that helps soothe irritation in the airways. It also contains cineoles, a compound with mucus thinning and antimicrobial properties, which supports clear airways and fighting infection. Rosemary leaves contain around 0.05 to 0.5% camphor, which support its use as a decongestant and expectorant.
