Cosmetic and/or pharmaceutical compositions and their applications
Compositions are disclosed containing, as active ingredients, an extract of Allium species, an extract of Citrus species and either an extract of Paullinia species and an extract of Theobroma species, or an extract of Salix species and zinc sulphate, and the method of preparation of these compositions, and cosmetic and/or pharmaceutical application of these compositions.
1. A composition comprising: from 65% to 93% of an aqueous-alcoholic extract of Allium species; from 5% to 33% of an aqueous-alcoholic extract of Citrus species; from 0.25% to 2.5% of an aqueous-alcoholic extract of Paullinia species; and from 0.25% to 2.5% of an aqueous-alcoholic extract of Theobroma species.
2. The composition according to claim 1 , wherein the Allium species is Allium cepa , the Citrus species is Citrus lemon , the Paullinia species is Paullinia cupana , and the Theobroma species is Theobroma cacao.
3. The composition according to claim 2 , comprising approximately 87% of the aqueous-alcoholic extract of Allium cepa , approximately 12% of the aqueous-alcoholic extract of Citrus lemon , approximately 0.5% of an atomized aqueous-alcoholic extract of Paullinia cupana and approximately 0.5% of an atomized aqueous-alcoholic extract of Theobroma cacao.
4. A medicine containing the composition according to claim 1 , wherein the medicine stimulates and encourages the regrowth of hair.
5. A method for the preparation of the composition according to claim 1 comprising:
preparing an aqueous-alcoholic extract of Allium species, an aqueous-alcoholic extract of Citrus species; an aqueous-alcoholic extract of Paullinia species; and an aqueous-alcoholic extract of Theobroma species;
combining the aqueous-alcoholic extract of Allium species and the aqueous-alcoholic extract of Citrus species to form a first solution;
mixing the first solution with the aqueous-alcoholic extract of Paullinia species; and the aqueous-alcoholic extract of Theobroma species to obtain the composition.
6. The method of preparation according to claim 5 , further comprising preparing the first solution by picking, cleaning, milling and macerating the Allium species and the Citrus species for several hours in an aqueous-alcohol, filtering the mixture to form an aqueous extract, adjusting the aqueous-alcoholic extract and mixing with the other ingredients.
7. A method for treating the hair and/or scalp of a subject comprising administering to the hair and/or scalp of the subject the composition according to claim 1 , wherein the treatment provides for at least one of:
slowing down the loss of hair;
stimulating hair growth;
