Therapeutic Properties
Chemistry
Primary Constituents
Citral (geranial + neral, 90-98%), 6-methylhept-5-en-2-one (1-3%), isopulegol, myrcene (trace) per Tisserand & Young 2014
Emotional & Psychological
Lemon Myrtle is strongly uplifting and mood-brightening, cutting through mental fog, apathy and emotional heaviness. Despite its bright profile, its high citral content also produces a paradoxical calming effect, useful for nervous exhaustion and low mood accompanied by agitation. It encourages clarity, focus and a renewed sense of brightness during depressive or stagnant periods.
Physical Therapeutic Uses
Lemon Myrtle demonstrates exceptionally strong antimicrobial activity against bacteria (including MRSA in vitro), fungi and viruses, making it valuable in surface cleaning, air purification and diffusion for infectious illness. It supports the immune system and clears stagnant air. Topical use for skin conditions must be extremely cautious due to citral-driven sensitization; diffusion is the preferred application.
