Well I have had all of the above. This year. And let me tell you if you didn't know this Australian Oil is multipurpose! Tea tree oil is obtained by steam distillation of the leaves of Melaleuca alternifolia.
The worst pain I ever felt in my life was jock itch (fungal infection) that went improperly diagnosed by my VA hospital. The doctor said chaffing take time off. The custodian said Jungle Rot. Guess who was closer?
Tingling Tea tree Oil body wash clears up all my skin problems fast. For exrteme cases I have the oil and I use a cue-tip to apply. A fever blister(Thanks Nanny!) Or was it that Thai Girl In Pattaya? Anyway They would go on for a week, and explode. With the tea tree oil many times a day, The stop hurting, and scab the first day. Not a huge mark either, Just a smal oops shaving accident

Terpinen-4-ol is the chemical in tea tree oil that makes it so effctive. Only recently scientists have discovered that it has Anti bacterial,antiviral,antifungal,...it cures scabies, lice,dandruff, cold sores, achne, jockitch, yeast infections... It can prevent Staff(MRSA) Chicken pox,shingles, herpes,blisters.... and On and on...

According to the American Cancer Society: "Tea tree oil is toxic when swallowed. It has been reported to cause drowsiness, confusion, hallucinations, coma, unsteadiness, weakness, vomiting, diarrhea, stomach upset, blood cell abnormalities, and severe rashes. It should be kept away from pets and children. I dont think you should be making Deca with it either. Dont inject this oil!!!

Also some people develop contact dermatitis from it so test it on your arm before putting it on your balls, or lips I would think.
