Manuka (Leptospermum scoparium)

What is Manuka?

In New Zealand, where manuka trees grow, the Maori consider male tea tree plants "Kanuka" and the female plants "Manuka". The plant is regarded very highly in this culture as a medicinal species.

The most well-known form of manuka is in manuka honey. This is a honey made by bees feasting primarily on manuka bushes. The honey has an impressive antibacterial profile when made from these plants. This is also reflected in the herb itself, which has been shown to have potent antibacterial, anti-fungal, and antiviral activity.

Most of the medicinal benefits of the plant come from its essential oil content, which can vary a lot depending on the region the plant was grown in.

 

What is Manuka Used For?

Internally, manuka is used to treat gastrointestinal conditions like diarrhea, colic, inflammatory bowel syndrome, and dysentery. It's also used for urinary tract infection, anxiety, and cold/flu infections.

Manuka is used topically for its antibacterial, and vulnerary actions. It's used to treat slow healing skin and bone injuries, bacterial infections, candida, and eczema. It can be gargled for gingivitis, or for general oral hygiene.

Manuka honey is another common form of the plant. It's become so popular worldwide, it's been standardised by the phenol content. This is expressed as a unique manuka factor (UMF) value set by the Active Manuka Honey Association (AMHA). Anything over UMF 5 is considered strong enough to kill MRSA.
