Scientific Studies - Gram Positive Bacteria
Scientific studies demonstrate New Zealand East Cape Manuka tea tree oil to be highly effective against a range of bacteria and fungi even at very low concentrations
The Cawthron Institute testing showed NZ East Cape Manuka tea tree oil to be active against a wide range of micro-organisms that cause irritation and infection of the skin and body.
Some of these bacterial micro-organisms are serious such as MRSA (more commonly known as the H-bug) while others are more common, such as fungi which cause Athletes foot.
The Cawthron Institute concluded that East Cape Manuka tea tree oil was 20 - 30 times more active than Australian tea tree oil against gram positive bacteria. Further testing has confirmed that East Cape Manuka tea tree oil is effective in combating bacteria including those associated with acne, and combating fungi that cause Tinea (Athletes foot), foot and body odour.
Comparison of effectiveness of NZ East Cape Manuka tea tree oil and Australian tea tree oil against selected bacteria
Please Note: The graphs shown here are expressed in minimum inhibitory concentration (MIC) (ie the lowest concentration which will inhibit the growth of a specified organism) therefore the shorter the bars are on the chart, the more effective the product will be in controlling the organism.

TAIRAWHITI (EAST CAPE) MANUKA OIL has been independently tested against a wide range of organisms and has been found to be active against all of those tested.
The minimum inhibitory concentration (MIC) (ie the lowest concentration which will inhibit the growth of a specified organism) was determined. A list of some of these follows:
