Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Leptospermum scoparium, commonly known as manuka, has a long history of traditional use among the Māori people of New Zealand and indigenous Australians. Traditionally, various parts of the plant—including leaves, bark, and oils—were used to treat a variety of ailments, including respiratory tract issues such as colds, coughs, and sinus congestion. Infusions and inhalations made from manuka leaves were used to help ease breathing and clear sinus passages, and manuka was valued for its aromatic and antimicrobial properties.

However, scientific studies specifically evaluating the efficacy of manuka or its extracts for supporting sinus health are limited. While manuka essential oil and honey are well-documented to possess antimicrobial, anti-inflammatory, and antioxidant properties, most scientific research has focused on their applications in wound healing, skin infections, and oral health. There is some indirect support for its use in sinus support due to its antibacterial effects against common respiratory pathogens, but robust clinical trials in the context of sinus health are lacking. Thus, while the traditional use of Leptospermum scoparium for supporting the sinuses is well established historically, scientific validation for this specific use remains weak.
