Traditional herbal oils
Herbal oils also called herbal oil extracts are traditional herbal remedies used to treat skin conditions, nourish and revitalize the skin. Beneficial effects are achieved through the combination of nutrients, antioxidants and biostimulants obtained from herbs using gentle nondestructive oil extraction techniques
What is the difference between herbal oils obtained by expression, solvent extraction, steam distillation or other methods? The overall content of oils in some herbs is not high enough to jastify use of a press. On the other hand, steam distillation works only for volatile ingredients and may inactivate some temperature sensitive bioactive nutrients, essential for the therapeutic action. Extraction with organic solvent is frequently used for the manufacturing of food additives and flavors from the herbs. Apparently, no one will argue that direct oil extraction is preferable to organic solvents for the skin care products. Supercritical CO2 extraction is sometimes mentioned as a viable alternative to oil extraction. At the same time, it has been shown that chemical composition of supercritical CO2 extracts is not identical to that of oil extracts of the same origin. Thus, CO2 extracts may be depleted in certain nutrients, found in the oil extracts, and responsible for the health beneficial action. To illustrate the difference from CO2 extracts, one may compare herbal oil extract to coffee, brewed from the freshly grounded beans, and CO2 extracted oil to an instant coffee. In fact, extracts made with organic solvents or CO2 lose some volatile and semivolatile ingredients, just like in case of an instant coffee. Volatile ingredients may be essential for expected biological effect. In fact the whole concept of aromatherapy is based on the action of volatile substances.
Last, but not least, herbal oils utilized in traditional herbal medicine are all obtained with vegetable oil extraction, the only available method at those times. Similarly, the limited amount of research and clinical trials available today, was conducted using herbal oil obtained by extraction of herbs into the vegetable oils. Therefore, all knowledge of healing effects of herbal oil, acquired over the centuries of trials and mistakes, are applicable only to oil extracts, until proven otherwise. Finally, clinical trials and scientific research demonstrating biological activity, therapeutic efficiency and safety of herbal oil extracts, conducted during last century, were not reproduced with CO2 extracts. Thus, at best it remains to be seen, how good are CO2 extracts as a substitute for traditional oil extracts.
