The work highlights the action of 9 natural substances and the colloidal Cu solution on Candida Albicans cultures. Observations were made at time intervals of 24, 48, 72, 96 and 120 hours. We noticed favorable results in the inhibition of Candida Albicans cultures after applying oregano oil, respectively copper colloidal solution, as well as cinnamon and geranium oils, for a short period of time. Candida albicans cultures remained unchanged in contact with the oils of: white musk, hemp, opium, cultivated thyme (Thymus vulgaris) and sandalwood, in a concentration of 20 %, as well as in contact with liquorice tincture (roots of Glycyrrhiza glabra).
