Manuka Essential Oil
Manuka Essential Oil is also known as New Zealand Tea Tree Essential Oil.
I first fell in love with Manuka Essential Oil back in the 1990s. Although it's also known as New Zealand Tea Tree Essential Oil and shares many of the same therapeutic benefits as Australian Tea Tree Essential Oil (Melaleuca alternifolia), the aroma of Manuka Essential Oil does not have the medicinal aroma that Tea Tree does.
Aromatically, Manuka Essential Oil is earthy, yet fresh and pleasant.
I tend to use Australian Tea Tree for those times that I need it strictly for physical or skin care applications. Because Manuka Essential Oil is a bit more costly, I tend to choose it for those times in which its aroma and emotional benefits will come into play.
Emotionally, Manuka Essential Oil tends to be a balancing and soothing essential oil that is grounding when needed. Although it cannot be closely compared to the smell of the earth after a fresh summer rain, smelling Manuka Essential Oil brings me a similar sense of joy and peace when I inhale it. Within his Manuka Essential Oil Profile, Salvatore Battaglia shares that "Von Braunschweig says that manuka is a protective oil similar to myrrh and cedarwood. She says that old psychic scars get smoothed and that the sesquiterpenes stabilise and protect the nervous system and balance the sympathetic and parasympathetic nerves. Manuka's vitalizing scent is well suited to gentle souls who express themselves through sensitive skin or frequent digestive upsets." [R. Von Braunschweig. Manuka, Kanuka and Tea Tree Oil - 3 Eessential Oils with Interesting Effects on the Psyche. Proceedings of the Australiasian Aromatherapy Conference, Sydney, 1998.

Manuka Essential Oil blends well with essential oils in the wood, citrus, herbaceous, spice, mint and medicinal families. Although I characterize it as a middle note, I do find that it possesses characteristics of a base note, and it makes a good bridge between middle and base notes within natural fragrancing and blending applications.
Like many essential oils, Manuka Essential Oil can vary in its composition based on where the tree is grown. However, I've noticed that most Manuka Essential Oils that I've seen to date are particularly abundant in sesquiterpenes (50-70%) followed by approximately 20% ketones with single percentages of sesquiterpenols and monoterpenes. In comparison, Australian Tea Tree Essential Oil (Melaleuca alternifolia), is most abundant in monoterpenes and monoterpenols with a small amount of oxides (particularly 1,8 cineole).
The composition of Manuka Essential Oil lends it to possess a much longer shelf life than Australian Tea Tree essential oil.
