Characterization of essential oil and effects on growth of Verbena gratissima plants treated with homeopathic phosphorus

Nat Prod Commun. 2011 Oct;6(10):1499-504.


Plant models offer a method to examine the efficacy of homeopathic solutions. Homeopathic Phosphorus (P) dynamizations were evaluated on the linear growth and dry biomass of Verbena gratissima, a plant native to Brazil. The yields and chemical characterization of the essential oil are also given. Plants exhibited phenotypic plasticity after the homeopathic Phosphorus treatments. The dynamization 9CH, in particular, interfered with plant growth, height, diameter of stems and total dry mass. 9CH treatment showed the highest yield of essential oil. The essential oil composition of V. gratissima varied according to the different dynamization used. Homeopathic Phosphorus provided the greatest amount of beta-pinene, trans-pinocarveol, trans-pinocamphone and trans-pinocarvyl acetate in comparison with controls.
