The water-soluble components of tea tree oil can suppress pro-inflammatory mediator production by activated human monocytes.

Tea tree oil components suppress the production of superoxide by monocytes, but not neutrophils, suggesting the potential for selective regulation of cell types by these components during inflammation.

The combination of lenalidomide and DVd chemotherapy was well tolerated and resulted in high response rates in this mostly refractory patient population. Evaluation of this combination in newly diagnosed patients is warranted.

Topical application of TTO, and in particular terpinen-4-ol, may be effective in controlling histamine-induced oedema often associated with Type I allergic immediate hypersensitivities.

Topical TTO, specifically the TTO components, terpinen-4-ol and alpha-terpineol can regulate the oedema associated with the efferent phase of a contact hypersensitivity response.
