Melaleuca alternifolia, commonly known as tea tree oil, has been explored as a treatment for psoriasis due to its anti-inflammatory and antimicrobial properties. The rationale behind its use is primarily scientific, though the evidence is limited and not robust. Several small-scale studies and case reports suggest that tea tree oil may help reduce inflammation and scaling in psoriatic lesions. Laboratory studies have demonstrated that terpinen-4-ol, the main active component in tea tree oil, can modulate inflammatory pathways, such as inhibiting the production of pro-inflammatory cytokines (e.g., TNF-alpha, IL-1β), which are implicated in the pathogenesis of psoriasis.

A few clinical trials and anecdotal reports have indicated that topical application of diluted tea tree oil may provide symptom relief, decrease itching, and improve lesion appearance in some patients. However, these studies often suffer from small sample sizes, lack of blinding, or insufficient controls. Meta-analyses and systematic reviews have generally concluded that while there is some scientific basis for its anti-inflammatory effects, the overall quality of evidence remains low, and more rigorous research is required.

It is also important to note that tea tree oil can cause allergic reactions or skin irritation, especially if used undiluted. Therefore, it is generally recommended as an adjunct rather than a primary treatment for psoriasis. In summary, tea tree oil's use for psoriasis is supported by limited scientific evidence, primarily from laboratory studies and preliminary clinical reports, but is not yet considered a mainstream or strongly validated therapy.
