Abstract
Water-soluble plant extracts, and fractions separated from such extracts by chromatography, which provide an antioxidant effect when applied to the skin, are utilized in a method of treating virus skin infections and resultant skin conditions, e.g. warts. Preferred plants are Trifolium, Medicago, Nicotiana, Zea, Pennisetum, Algae and Allium, and members of the order Chenopodiales such as the families Chenopodiaceae and Aizoaceae.
Claims38
A method for treating warts, which comprises applying to skin having warts thereon, a water soluble antioxidant material of plant origin which is characterized by stability for an extended period of time under ambient temperature and pressure, at least in the dry state, and by the fact that it provides an antioxidant effect when applied to the skin, said material of plant origin having been obtained by a step of water extraction of tissue selected from stem and leaf tissue from plants selected from the group consisting of Trifolium, Medicago, Nicotiana, Zea, Pennisetum, Algae and Allium, and members of the order Chenopodiales.
A method for treating warts, which comprises the steps of:
- comminuting plant tissue selected from fresh leaf and stem tissue of plants selected from the group consisting of Trifolium, Medicago, Nicotiana, Zea, Pennisetum, Algae and Allium, and members of the order Chenopodiales;
- extracting thus comminuted tissue with water at a temperature between about 4.degree. C. and the boiling point of the mixture of water and comminuted tissue, to obtain a crude aqueous extract;
- subjecting the crude aqueous extract to chromatographic separation;
- testing for antioxidant activity a material selected from the group consisting of the crude aqueous extract and the fractions obtained by said chromatographic separation step;
- selecting a material from the tested group which gives a positive result in said testing step;
- and
- applying to skin having warts thereon, at least one material which is thus selected.
A method for treating warts, which comprises the steps of:
- extracting with water plant tissue selected from leaf and stem tissue of plants selected from the group consisting of Trifolium, Medicago, Nicotiana, Zea, Pennisetum, Algae and Allium, and members of the order Chenopodiales, to obtain a crude aqueous extract having antioxidant activity;
- subjecting the crude aqueous extract to chromatographic separation, to obtain fractions having antioxidant activity;
- and
- applying to skin having warts thereon at least one material selected from the group consisting of said crude aqueous extract and said fractions.
