Description

MEDICAMENTS AND COSMETICS FOR TREATING SKIN AND HAIR CONDITIONS This invention relates to medicaments and cosmetics for treating skin conditions including but not exclusively dermatitis, psoriasis and eczema. The invention also has utility in cosmetic hair treatment by reversing greying.

Psoriasis and eczema cause much distress. Those afflicted suffer from discomfort and pain occasioned by the disease. The degree of discomfort is perhaps not full appreciated by those having the misfortune to suffer. Psoriasis is characterised by unsightly circumscribed red skin patches covered with white scale.

Eczema is characterised by, sometimes intense, itching, redness and oozing vesicular lesions. Those affected suffer not only from as it were the medical effects of the complaint but also the physical effects. Sufferers can be very upset by their physical appearance in that d-amage is done to the self-image and also the sufferer feels that he or she is being stared at by others.

Eczema while having an indeterminate number of causes is known in may cases to be aggravated by stress. It is possible that a vicious circle can ensue. A person may suffer from a small conspicuous patch of eczema. The stress occasioned by loss of self-image and real or imagined looked from by-passers leads to further spreading and so on.

Greying of hair so far as is known causes no damage to the body. The damage to the ego can be notoriously severe.

The invention seeks to alleviate the symptoms of these complaints in at least some cases. It must however be appreciated that neither psoriasis, dermatitis nor eczema may properly be considered to be single disease.

A more accurate analysis is that the complaints are constellations of similar symptoms invoked by a variety of causes. Accordingly alleviation can not be expected in all cases. Nevertheless the invention has more than a placebo effect.

According to the invention there is provided Cedrus spp leaves as a medicament.

According to the invention is provided the use of Cedrus spp leaves in the manufacture of a medicament for the treatment of psoriasis, eczema or dandruff.

According to the invention there is provided a method of improving the appearance of a mammal afflicted by psoriasis, eczema, dandruff or by topical application of Cedrus spp leaves.

Both gum tragacanth and cedrus compositions are also effective in reducing skin inflammation, non specific erythrema and itching. It may be desirable to apply them for example to sun-burn as cooling compositions. Both compositions are usuable as skin cleansers for sensitive skin and are effective as excortication agents.

Cedrus spp leaves have also been found to have utility in alleviating the aforementioned conditions.

Cedrus leaves are collected from a range of species especially Cedrus libani primarily from the Middle East including Iraq and Iran. The leaves are dried at low temperature and crushed to give a fine, pale green powder. Because Cedrus spp are not deciduous and leaves are always in a range of states of development the time of harvesting is not of crucial importance. A decoction of the powder prepared with hot water is pale coloured.

When applied o the skin it has been found to reduce inflammation especially when caused by psoriasis or eczema. Application may be required daily or thrice weekly for some time before a significant improvement is noted.

The following compositions are non-limiting examples Ingredient Amount/ml Powdered dried cedrus 5 Deionized Water 200 Warm water at 450C is poured over the powder and stirred. The liquor rapidly acquires some colour but is allowed to cool by standing. The liquor is decanted from the powder. Afflicted skin areas are bathed with the liquor. After allowing contact for about five minutes the skin is patted dry.

The cedrus may be incorporated into a conventional shampoo or cream base for application. Ethanolic or other organic extraction of the leaves results after removal of the solvent in an oil which is efficacious. The oil or powder or decoction may be incorporated in any base for topical treatment. Examples include the shampoo bases hereinbefore described with or without the gum, preservative and citrate. Application to the hair can reduce or reverse age-related greying of the hair.

Suitable strengths of decoction can be found by routine experiment. It is unlikely that any significant extra benefit can be obtained by using more than 20% cedrus (based on dry powder to final composition by volume). Similarly less than 0.5% is unlikely to have significantly greater than placebo effect. Preferred amounts are in the range of 1 to 15%, more preferably 2 to 10%, especially 3 to 6%.

The cedrus leaves may be presented in other forms.
