FROM INDIGENOUS KNOWLEDGE TO SCIENTIFIC DATA
The idea emerged a few years ago, when epidemiological observations in areas of Crete showed that people who consumed infusions of certain herbs had low rates of ill-health and rarely suffered from common cold and/or flu. The study, which was conducted by researchers from the University of Crete, was published in the internationally renowned medical journal The Lancet. The efficacy of herbs was attributed to their antioxidant properties (Lionis C. et al. Antioxidant effects of herbs in Crete. Lancet 1998, Vol. 352).
The emphasis placed by indigenous knowledge on the beneficial action of selected herbs on upper respiratory infections drove the scientists to the next step. After many years of trials, research revealed a combination of essential oils from three herbs, Coridοthymus capitatus, Salvia fruticosa and Origanum dictamnus, working synergistically in specific proportions. The subsequent clinical trial involving 105 participating patients with symptoms of upper respiratory viral infection demonstrated beneficial effects (G. Duijker, A. Bertsias, E. Symvoulakis, J. Moschandreas, N. Malliaraki, S.P. Derdas, S.A. Pirintsos, G. Sourvinos, E. Castanas, C. Lionis.
