Nettle leaf is often used to help reduce allergy symptoms because it may help the body regulate histamine release, which is a key trigger for sneezing, itching, and congestion. It also contains natural anti-inflammatory compounds and minerals that can support the immune system’s response to allergens, potentially making reactions less intense over time.

Mullein leaf is commonly used for respiratory allergies because it helps soothe and coat irritated mucous membranes in the throat and airways. Its gentle anti-inflammatory and expectorant properties may help loosen mucus, reduce congestion, and make breathing feel easier when allergies affect the sinuses or lungs.
