Natural pharmacopoeia used in traditional Toba medicine for the treatment of parasitosis and skin disorders (Central Chaco, Argentina).

AIM OF THE STUDY

To assess the knowledge and use of natural pharmacopoeia for the treatment of parasitosis and skin disorders, as well as for the control of their etiological agents or vectors, of a Toba community in Central Chaco, Argentina.

MATERIALS AND METHODS

Information was obtained by open, extensive and recurrent interviews and semi-structured surveys. Plant and animal pharmacopoeia was documented by collecting material in field assays carried out in the company of informers. The list of applications with the greatest consensus of uses, the list of species with most medicinal applications and the list of species with the highest reputation (according to the level of fidelity) for the aforementioned disorders were obtained using quantitative methods.

RESULTS

A total of 178 medicinal uses were documented corresponding to 87 species (72 plant and 15 animal species) belonging to 51 different families (39 plant and 12 animal families). The most represented families according to the number of species were Solanaceae (7 species), Asteraceae (6 species) and Fabaceae (5 species) for plants, and Bovidae (3 species) for animals.

CONCLUSIONS

Although the list of medicinal species includes some symbolical applications, others are supported by phytochemical information. In other cases the applications coincide with other pharmacopoeias of the Gran Chaco region indicating the presence of an active exchange of knowledge through interethnic contacts.
