Geraniol: A terpene alcohol. Fragrant and regarded as highly
valued oil in aromatherapy and the perfume industry. Terpene alcohols are
antimicrobial but are a lot gentler on the skin than the phenols.
Linanool: Linalool one of the terpene alcohols is widely
distributed in the plant kingdom. Linalool has strong effects on the nervous
system and is therefore widely used by aroma therapists and herbologists as a
sedative, spasmolytic and local anaesthetic. It is also used against many skin
complaints, mostly in the form of tea tree oil.
Limonene: Limonene has been studied for the anti-tumour effect
noticed in mice. Herbalists often prescribe herbs with this constituent as an
antioxidant and cancer or tumour inhibitor although there is evidence that these
properties are volatile and may be lost as a result of processing of the herb.
Limonene also has antiviral properties.
