Lemongrass, also known as fever grass, is an herb with a fresh, lemony scent. It’s called fever grass because it’s traditionally considered to be anti-pyretic (anti-fever) by stimulating the body to sweat, though I couldn’t find any studies to corroborate this.

Lemongrass is possibly best known as citronella, for the role of its essential oil as a bug and mosquito repellant.

Like nearly all medicinal herbs, it is very high in antioxidants and flavonoids. It’s also (like nearly every medicinal herb) antimicrobial and anti-inflammatory. But it does shine for a few additional properties in particular, as well. 

Lemongrass for Fungal Infections

While lemongrass’s efficacy against fungi falls under the category of “antimicrobial,” the essential oil has been specifically studied against various kinds of candida and aspergillus, with impressive results, especially against candida albicans. 

Treatment of yeast overgrowth generally needs to happen at the level of the gut for lasting results, but lemongrass essential oil (diluted appropriately with a carrier oil) can be used topically for fungal skin infections. 

Lemongrass for Dental Infections 

As mentioned, lemongrass is antimicrobial, which also includes anti-bacterial. This study shows that lemongrass essential oil is effective against strep mutans, the bacterial responsible for dental caries.  

To protect against cavities, or even to try to reverse them, lemongrass tea might be a good choice, or perhaps adding a few drops of lemongrass essential oil to your coconut or sesame oil for oil pulling. 

Lemongrass for Hypertension (and maybe EMF Sensitivity)

When researching natural substances that might protect against EMF, I came across the fact that lemongrass is a natural calcium channel blocker. This should help aid against EMF toxicity, since so far as we can tell, one of the primary mechanisms by which EMF damages the body is through disruption of the calcium channels. 

Calcium channel blockers are also a common class of drugs used for blood pressure regulation. Additionally, lemongrass has diuretic properties, which can reduce blood pressure by lowering blood volume—so lemongrass can help to control blood pressure via multiple mechanisms.

Cautions

If you’re using lemongrass essential oil, as with all essential oils, make sure you dilute with an appropriate carrier oil to avoid burning your skin. 

One of the constituents of lemongrass, citral, is considered potentially toxic during pregnancy so should be avoided.
