Many different types of bacteria can cause PID. Most often, PID is caused by infection from two common STIs: gonorrhea and chlamydia. The number of women with PID has dropped in recent years. This may be because more women are getting tested regularly for chlamydia and gonorrhea. You can also get PID without having an STI.
It's fairly common for people to use tea tree oil for warts, although care should be taken to avoid skin irritation. While some people prefer to apply the oil directly to the warts, health care practitioners usually suggest diluting it first with water or a carrier oil, such as olive or almond oil.
You can usually find products made with tea tree oil at natural food stores and at some pharmacies. When it comes to common scalp problems like hair loss, dry skin, dandruff and head lice, tea tree oil may be an effective natural alternative to harsh chemicals. In shampoo form, it may be effective in reducing dandruff, unclogging hair follicles and clearing up bacterial and fungal infections [source: Olsen ].
