- Essential Oils
- Including myrcene, limonene, and cineole, these aromatic oils have antimicrobial, expectorant, and calming effects.
- Resins
- Sticky substances contributing to wax myrtle’s wound-healing, anti-inflammatory, and antimicrobial actions.
- Saponins
- Natural surfactants that help with expectoration, cleanse tissues, and promote mild detoxification.
- Phenolic Acids
- Offer further antioxidant protection and contribute to the plant’s cleansing effects.
