Thymol, the primary constituent of thyme is rapidly absorbed in
the upper gastrointestinal tract. Preliminary research suggests
that thyme has antimicrobial activity and modest antibacterial
effects.149,150 It also seems to have antiviral
activity.151 Other preliminary research suggests
thyme has activity against fungi such as Candida albicans and
other Candida species.
Thymol is active against fungal microorganisms that cause fungal
Thyme and its constituents may have antioxidant
effects.149,153,154 The antioxidant effect of thyme
may increase the production of nitric oxide and improve
atherosclerosis and endothelial dysfunction.155
Research suggests thyme has antispasmodic, antiplatelet,
anti-inflammatory, and antiallergic
activity.156,157,158,159 Additionally, thyme might
improve wound healing.160
Orally, thyme is generally well tolerated. Gastrointestinal
