Here is the info on Tea Tree Oil, it is a traditional herbal antiseptic / germicide. Mainly use for the treatment of minor skin aliments and abrasions.
You will find it as the main ingredient in many natural products use for cleaning and disinfection.
Tea tree oil is the essential oil steam distilled from the Australian plant Melaleuca alternifolia. It has also been known as melaleuca oil. Tea tree oil contains over 100 components, mostly monoterpenes, sesquiterpenes and their alcohols. The component terpinen-4-ol is the most abundant (minimum 30%) and is said to be responsible for most of the antimicrobial activity. Levels of 14 components, including terpinen-4-ol are stipulated in the International Standard for Oil of Melaleuca, Terpinen-4-ol type (ISO 4730).
MRSA are Staphylococcus aureus bacteria that have become resistant to several antibiotics including methicillin. MRSA can infect people and cause disease, or can simply colonise the skin of healthy people without doing them any harm. MRSA infections are often serious and life-threatening while MRSA colonisation is not usually a problem for the carrier.
We know that TTO can inhibit and kill MRSA in the lab. There is also mounting evidence that it may be useful for eliminating the topical carriage of MRSA. On the current evidence, it is unlikely that TTO will be used to treat systemic MRSA infections although it may find a use in treating wounds infected or colonised with MRSA.
Folklore also claims that TTO is effective in controlling fleas, ticks, lice, and although has a rather distinctive smell has been used to eliminate/neutralise other offensive smells.
Placing a few small drops in warm water, and putting in a spray bottle, is a quick and simple way to disinfect your dogs paws, coat. Many dog exhibitors familiar with TTO also use it as a coat conditioner, mosquito repellent. It's uses by the herbal community are wide and varied.
TTO is only ever to be used topically and never swallowed or used as mouth wash. The taste alone should deter this, but large amounts (based dependant on weight of digester), are toxic.
There are many web sites both scientific and homeopathic that have further information of TTO. If you wish to investigate this product more fully.
