White Nettle (Lamium album), also known as dead-nettle, has been used in traditional European herbal medicine for a variety of ailments, including respiratory complaints such as sinus congestion. Folk herbalists have prepared infusions or teas from its leaves and flowers, believing it to possess mild astringent and anti-inflammatory properties that might help soothe mucous membranes and reduce congestion. However, the evidence supporting its efficacy for treating or alleviating sinus congestion is largely anecdotal, with references found in older herbal texts and ethnobotanical accounts. There is little to no clinical or preclinical (animal or laboratory) research directly investigating the effects of White Nettle on sinus congestion or its mechanisms of action for this particular symptom. Modern herbal references sometimes list it among herbs used for upper respiratory tract support, but these recommendations are primarily based on historical use rather than scientific studies. In summary, the use of White Nettle for sinus congestion is supported by traditional use, but there is minimal scientific validation, and the strength of evidence is low.
