Preclinical toxicological assessment of a phytotherapeutic product - CPV (based on dry extracts of Crataegus oxyacantha L., Passiflora incarnata L., and Valeriana officinalis L.)
Associations of plants have been widely used, for centuries, in Ayurveda and in Chinese medicine and have been increasingly acknowledged in Western medicine. the objective of this study is to assess the level (of toxicity of an association of three plants: Crataegus oxyacantha, Passiflora incarnata,...

| Sumario: | Associations of plants have been widely used, for centuries, in Ayurveda and in Chinese medicine and have been increasingly acknowledged in Western medicine. the objective of this study is to assess the level (of toxicity of an association of three plants: Crataegus oxyacantha, Passiflora incarnata, and Valeriana officinalis (CPV extract). This association was administered to rats, mice, and dogs, both acute and chronically for 180 days. the tests used in the acute experiments were: observational pharmacological screening, LD(50), motor coordination and motor activity. Chronic tests carried out were: weight gain/loss and behavioral parameters in rats and in mice; estrus cycle, effects on fertility, and teratogenic studies in rats and of mutagenic features in mice, in addition to the Ames test. the following parameters were assessed in dogs: weight gain/loss, general physical conditions, water/food consumption and anatomopathological examination of the organs subsequent to the 180 days of treatment. All of the results were negative, showing that CPV administered in high doses and over a long period of time presents no toxicity, suggestive of the fact that this is an association devoid of risk for human beings.
