ABSTRACT Finding an effective treatment for acne that is well tolerated by the patients is a challenge. One study has suggested the efficacy of tea tree oil in treatment of the acne vulgaris.
To determine the efficacy of tea tree oil in mild to moderate acne vulgaris.
This was a randomized double-blind clinical trial performed in 60 patients with mild to moderate acne vulgaris. They were randomly divided into two groups and were treated with tea tree oil gel (n=30) or placebo (n=30). They were followed every 15 days for a period of 45 days. Response to treatment was evaluated by the total acne lesions counting (TLC) and acne severity index (ASI). The data was analyzed statistically using t-test and by SPSS program.
There were no significant differences regarding demographic characteristics between the two groups. There was a significant difference between tea tree oil gel and placebo in the improvement of the TLC and also regarding improvement of the ASI. In terms of TLC and ASI, tea tree oil gel was 3.55 times and 5.75 times more effective than placebo respectively. Side-effects with both groups were relatively similar and tolerable.
Topical 5% tea tree oil is an effective treatment for mild to moderate acne vulgaris.

    • "Similarly, the mean reduction in acne severity index was 40.5% for the tea tree oil group compared with 7.0% for placebo. Pruritus was reported as an adverse event both in the tea tree oil (10% of patients) and placebo (6.7%) groups [17]. A study published in 2011 [18] compared three groups in an open-label study: (i) 5% tea tree oil gel; (ii) 5% tea tree oil gel and a polyherbal tablet; and (iii) polyherbal tablet alone [18]. "

    ABSTRACT: Over-the-counter acne treatments containing tea tree oil from the plant Melaleuca alternifolia are widely available, and evidence indicates that they are a common choice amongst those self-treating their acne. The aims of this review were to collate and evaluate the clinical evidence on the use of tea tree oil products for treating acne, to review safety and tolerability and to discuss the underlying modes of therapeutic action. © 2014 Elsevier B.V. and the International Society of Chemotherapy.

    ABSTRACT: Conventional non-surgical periodontal therapy has been proven to be an effective treatment for patients with chronic periodontitis. Tea tree oil (TTO) can be used as adjunct to conventional periodontal therapy in patient with chronic periodontitis. The aim of this study was to evaluate the effectiveness of adjunctive treatment of TTO on the clinical parameters and the level of pentraxin-3 (PTX3) in chronic periodontitis. A total of 40 patients with moderate to severe chronic periodontitis were divided into two groups, Group I received scaling and root planing (SRP) only, Group II received SRP and TTO gel. Clinical parameters were recorded and gingival crevicular fluid (GCF) samples were collected from each subject for measuring PTX3 levels at baseline, 1, 3 and 6 months after treatment. In all evaluation periods, there was statistically significant reduction in each of the studied clinical parameters and PTX3 level in Group II as compared with Group I. The local delivery of TTO gel in case of chronic periodontitis may have some beneficial effects to augment the results of the conventional periodontal therapy. Moreover, it places a focus on the value of monitoring GCF levels of PTX3 as a marker of periodontal tissue healing.

    ABSTRACT: Acne vulgaris is considered one of the most common disorders for which patients seek dermatologic care. In the current study, we evaluated efficacy of the 5% nicotinamide gel versus 2% clindamycin gel in the treatment of the mild-moderate acne vulgaris. This was a randomized, controlled clinical trial that was performed in 2009-2010. Sixty female patients with mild or moderate acne vulgaris were recurited to be treated either with 5% nicotinamide or 2% clindamycin gel for 8 weeks. Acne severity index (ASI) was used to evaluate response to treatment and SPSS software was used to analyze the data. The mean of ASI at the baseline was 16.85 ± 8.5 and 18.2 ± 12.27 in nicotinamide gel and clindamycin gel, respectively (P > 0.05). The mean of ASI was significantly decreased compared with baseline ASI during the time in both groups (P < 0.0001). However, there was not a significant difference regarding reduction of ASI between the nicotinamide and clindamycin gel (P = 0.583). Five percent nicotinamide gel is as effective as 2% clindamycin gel for treatment of mild to moderate acne vulgaris. No side effect was observed during the treatment.
