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.
Tea tree oil is toxic when taken by mouth. It is typically used as a topical medication in low concentrations for folk medicine treatments of skin conditions. Tea tree oil is claimed as useful for treating dandruff, acne, lice, herpes, insect bites, scabies, and skin fungal or bacterial infections. However, the quality of the evidence for efficacy in these conditions is minimal. Tea tree oil is neither a patented product nor an approved drug.
