Radioprotective Essential Oils
Essential oils have various actions that can protect against nausea and vomiting associated with radiation sickness. Some oils are also antioxidants, free radical scavenging, and antimutagenic. Some support protection of the skin against UV damage or healing of tissues that have been burned by radiation.
Radiation is an important modality in cancer treatment and estimates are that between one third and one half of all patients will require ionizing irradiation therapy during some point in their clinical management. However, the radiation-induced damage to the normal tissues restricts the therapeutic doses of radiation that can be delivered to tumors and thereby limits the effectiveness of the treatment. The use of chemical compounds (radioprotectors) represents an obvious strategy to improve the therapeutic index in radiotherapy. However, most of the synthetic radioprotective compounds studied have shown inadequate clinical application owing to their inherent toxicity and high cost. These observations necessitated a search for alternative agents that are less toxic and highly effective.
Rosemary is one of the popular antioxidants used for various ailments in different nation´s folk medicine as well as a beverage drink. Flowering tops and leaves have a camphor-like odour and taste, and are considered carminative, diaphoretic, diuretic, aperient, emmenagogue, stimulant and stomachic. Clinical studies also support that Rosemary is an excellent antioxidant, having antimicrobial, anti-mutagenic, radioprotective and chemopreventive properties (Al-sereiti et al.,1999; Sancheti and Goyal, 2006, 2006a, 2007, 2007a).
