  • Introduction

It is well known that the Essential Oil distilled from Leptospermum scoparium (Manuka Oil) has low toxicity and an excellent potency particularly against gram positive micro-organisms.

Melaluca (Australian Tea Tree) flowers

Tea Tree
It is also known that the Essential Oil distilled from Melaleuca alternifolia (Tea Tree Oil) has relatively low toxicity and a good potency, particularly against gram negative micro-organisms. Both oils also have quite strong distinctive perfumes.

  • Why LEMA® Oil?
There is a clear need for a natural, low toxicity, broad spectrum, high potency oil, with a low perfume level, particularly for use in cosmetics and medical applications, and for skin antiseptics.

  • What is LEMA® Oil?
LEMA® Oil is a mixture of the most microbiologically active fractions of Leptospermum scoparium oil (Manuka Oil), and the most microbiologically active fractions of Melaleuca alternifolia oil (Tea Tree Oil). The resulting oil is broad spectrum and potent, and also has reduced perfume.

  • In Cosmetics:
Such an oil could be used for its antimicrobial properties, and because of low use rates, any natural perfume associated with it would be diluted out.

  • In Medical Applications:
Essential Oils often help the healing process so LEMA® Oil being a broad spectrum, highly potent, low toxicity, antimicrobial could find many uses where tropical applications to combat infections are called for:
Such applications could include impregnation of gauze applied to trauma sites and skin infections.

  • In Skin Antisepsis:
In critical areas such as hospitals, it is increasingly vital to have access to highly effective, low toxicity broad spectrum preparations. LEMA® Oil can be incorporated in scrubs and hand sprays.
Increasingly food handlers are transmitting infection. Because of its high potency and low toxicity  LEMA® Oil offers an ideal active ingredient where repeated use calls for an effective antimicrobial which will not cause skin problems.
