Can the tea tree oil (Australian native plant: Melaleuca alternifolia Cheel) be an alternative treatment for human demodicosis on skin?

Australian tea tree oil (TTO) and its extract terpinen-4-ol (T4O) are found to be effective in moderating demodex-related diseases. Their possible effects are lowering the mite counts, relieving the demodex-related symptoms and modulating the immune system especially the inflammatory response. This review summarizes the topical treatments of TTO and T4O in human demodicosis, their possible mechanism of actions, side-effects and potential resistance in treating this condition. Although current treatments other than TTO and T4O are relatively effective in controlling the demodex mite population and the related symptoms, more research on the efficacy and drug delivery technology is needed in order to assess its potential as an alternative treatment with minimal side-effect profile, low toxicity and low risk of demodex resistance.

[Effects of Salvia miltiorrhiza on Chlamydia trachomatis mice of salpingitis].

OBJECTIVE: To study the effects of Salvia miltiorrhiza on treatment of Chlamydia trachomatis salpingitis (CTS) and fibrosis. METHOD: A mouse model for CTS was estahlished in C3H/He by intravaginal inoculation. after 3 weeks mice were randomly divided into 3 groups. Only Azithromyxin was given orally, Azithromyxin and early S. miltiorrhiza given, or Azithromyxin and later S. miltiorrhiza given. After 10 weeks, observe the change of oviduct of mice, observe the histopathologic change and analysis collagen histochemical index. RESULT: 3 Treatment groups induce tubal occlusion and hydrosalpinx decreased and the collagen histochemical index decreased significantly than those of no treatment given (P < 0.05). Early S. miltiorrhiza given group induce tubal occlusion and hydrosalpinx decreased and the collagen histochemical index decreased significantly than only Azithromyxin group or later S. miltiorrhiza given group (P <0.05). CONCLUSION: When we treat CTS genital infection with Azithromyxin, if we can give S. miltiorrhiza treatment as early as possible, it may decrease tubal occlusion and hydrosalpinx. significantly inhibit fibrosis maybe one of its pharmacologic mechanismin.
