Effects of homeopathic drugs Sulphur and Arsenicum album in growth variables and essential oil content of mint are analyzed. Four homeopathic dinamizations (6, 12, 24 and 30CH) were used for both drugs in the centesimal scale (CH=centesimal hahnemannian), besides control (water). Treatments were conducted in greenhouse and homeopathic drugs applied weekly (250 mL vase-1) for 98 days. Plant height, root system’s dry mass, shoot’s dry mass and essential oil content were determined. Among the tested homeopathy drugs, Sulphur increased values of fresh and dry biomass more than Arsenicum album. Plant height increased by the two drugs and their respective dinamizations. Whereas Sulphur inhibited dry biomass production, except 6CH dinamization, it increased substantially mint plant’s essential oil content. Arsenicum album presented the same behavior as Sulphur drug, with the difference that it increased the fresh biomass in 24 and 30CH dinamizations. Results suggest that Sulphur and Arsenicum album modify plant metabolism, especially by increasing secondary metabolism as occurs with essential oil contents
