Whatever it is you could make yourself some oleander skin creme by following the directions for the home remedy oleander soup and then further condensing the mixture and preparing as noted in the instructions:
For a basic skin creme or lotion: Slowly boil the original brew down to a light syrup, condensing the liquid and making it thicker at a less than boiling temperature.
Mix the final syrup with an aloe based hand cream, using one part oleander syrup to three parts hand cream. Used regularly, Dr. Ozel’s patent says this is a good topical cream for pre-cancerous skin cells, age spots, moles, and psoriasis.
When used for psoriaisis, it is most effective to mix the concentrated oleander with ozonated olive oil. It works even better if you mix it with ozonated grape seed oil although some people have a skin sensitivity to the more potent ozonated grape seed oil. (Olive oils sets like Vaseline after about 4 - 5 days of bubbling ozone through it while grape seed oil takes from 18 - 22 days. It is thus much more saturated with ozone).
