Stinging nettle is a commonly used herb which is often drunk in the form of a soothing, healthy tea. Studies have revealed that it may actually be an effective treatment against allergies.

One commonly cited study with 60 participants found that 58% of those who were treated with stinging nettles at a dose of 300 mg a day experienced a significant reduction in their allergic symptoms with 48% rating it effective when compared to their prescription medications.
