Need to the highest possible temperature that will give good quick results but not have a destructive effect on the constituents of the leaves. Kind Regards
To avoid any destruction to the secondary metabolites, a suggested temperature of 40 degrees is acceptable. However this might take quite a while before it dries. I did attempt drying at temperatures of 50 and 60 degrees. The results of my tests done thereafter was not as pronounced as when dried at 40 degrees
Abstract: A method of producing a Bulbine frutescens extract in a stable form by treating juice expressed from the leaves of the Bulbine frutescens plant with hydrogen peroxide, removing the remaining hydrogen peroxide and stabilizing the extract using a suitable stabilizer. The Bulbine frutescens extract is used in the therapeutic or cosmetic fields and has an especially good effect on diseases of the skin and mucous membranes, in particular infections or inflammations such as fungal diseases, in prevention and/or curing injuries to the skin and mucous membranes, in particular burn wounds, as a disinfectant, as an agent to improve the immune defense, for body care, oral care, as an antiperspirants and as an antiaging product. The effect is to some extent far superior to that of commercial products, and there is no damage to the natural microflora of the skin and mucous membranes but instead they remain intact. Furthermore, the appearance of the skin is greatly improved.
