manuka-Leptospermum-scoparium-cover.jpg

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.

Botanical Information

Magnolia officinalis is a medium sized tree, ranging from 5 to 15 m in height. It's deciduous, with purple brown bark.

Magnolia is a member of the Magnoliaceae family of plants. There are 2 subfamilies in this family, including Magnollioideae and Liriodendroideae. The latter of which only includes Liriodendron (Tulip trees). In The Magnoliaceae family there are approximately 219 species, distributed into 17 genera. The vast majority are included in the Magnolia genus, which has about 210 different species.

One interesting note is that it appears magnolia appeared before bees did. The flowers are instead evolved to be pollinated by beetles, due to the extremely tough carpels on the flower. There have also been fossils discovered with plants contained in the Magnoliaceae family as far back as 95 million years ago, making Magnolia one of the oldest remaining angiosperms.

 

Clinical Applications Of Magnolia:

Magnolia increases the activity of GABA receptors, as well as the muscarinic receptors. This is why Magnolia is useful for both its sedative effect, as well as some mild stimulating effects. While most anxiolytic herbs have a particular effect on the parasympathetic nervous system (through GABAergic effects), Magnolia also increases the activity of the sympathetic nervous system through the muscarinic acetylcholine receptors in a similar way to GABA.

Magnolia is especially useful for eliminating nasal congestion, sinus infections, coughs, and catarrh. It's used to improve indigestion and dysentery, though it is not commonly used for bacterial or fungal infections alone.

Magnolia is also used for reducing symptoms of stress and anxiety. It can reduce cortisol levels in stressed individuals, especially in combination with Phellodendron. Its primary actions for this involves GABAergic activities, and have been shown to lower salivary cortisol levels in stressed individuals.

Magnolia should be avoided in those who are chronically fatigued, or who are suffering from convalescence. Traditional Chinese medicine suggests that magnolia should be avoided with any condition involving yin deficiency.
