Herbs and the mechanism of influence:
The skin contains three layers: epidermis, dermis, and hypodermis: As for the epidermis, it is responsible for the color of the skin. It has pigment cells, basal, squamous, granular, and cornea cells. The epidermis is characterized by the presence of basket cells: responsible for the health assessment of the body’s nerves and blood vessels, transporting oxygen, nutrients, and important elements. Langerhans cells stimulate and awaken the immune system and the Pacini corpuscle is a neuroreceptor located in the layer. Subcutaneous fat responds to pressure or disturbance, sebaceous glands secrete fatty substances on the surface of the skin, and nerve cells that are responsible for feeling pain, heat, and cold. Sweat glands: moisturize the skin and have channels permeable to the outer surface. The dermis is full of capillaries responsible for heat and warmth, and the retina contains lymph nodes, which are the most important immune system of the skin. Collagen layer gives the skin strength and firmness, its deficiency leads to keratosis pilaris. The task of the dermis is to protect the skin from bacteria and germs by secreting fatty oils and transmitting messages and nerve impulses related to the sensation. Cutaneous absorption is one of the modes of exposure to bioactive substances, which includes treatment with herbal oils and medicines.
Absorption of substances through the skin depends on several factors, including:
- Concentration. - The atomic weight of the molecule. - The duration of skin contact with the drug. - The solubility of the drug. - The health and safety of the skin. - The exposed part of the body, including the amount of hair on the skin. - The following general chart shows the rate of absorption of substances from the fastest to the slowest: the forehead, the armpit, the scalp, the back and the abdomen, the soles of the hands (the palms), the soles of the feet. In contrast to swallowing and injection, the process of applying the drug to the skin allows the effect of the drug to be localized. Some medicines and treatments may be more effective and more efficient when the skin is used as a way to give this medicine. Some medicines taken orally are metabolized by the liver, resulting in a loss of part of the dose and consequently part of the efficacy and efficiency of the drug. However, applying such drugs to the skin and using the skin as a means of administration allows the drug to bypass this step and to enter a larger amount of it into the circulation. If the drug is well and sufficiently absorbed, transdermal administration can be relied upon to give a systemic effect. Dermatological dosage forms include: herbal oils, ointments, powders. plasters. The advantage of slow absorption through the skin - compared to absorption resulting from swallowing or injection - allows to provide the substance for a longer period ranging from 1 to 7 days .. Among these substances are polyphenols, flavonoids, and anthocyanins. Polyphenols are considered healthy substances necessary for the body. These substances are found in the fruits of aronia (a type of berry), grape leaves, grape fruits, olive oil, pomegranate, ginkgo, tea, wild sesame, and the bark of the pine tree. Polyphenols such as flavonoids are extracted from the bark of the cedar tree for medicinal uses. These substances have an effect like that of antioxidants, and they neutralize free radicals, and protect the skin from processes that cause skin aging and the formation of wrinkles. The effect of the anthocyanin exceeds the effect of vitamin C and vitamin E. Anthocyanin is found in olive oil, pomegranate, soy, green tea, and grapes. Some herbs have been used since ancient times to increase sweating, relieve sweating, treat pain, and benefit from some of the substances that the body needs, especially in cases of high fever with the aim of cooling and lowering the temperature. By expanding the capillaries and thus increasing the activity and flow of blood circulation. Elderberry: Elderberry contains flavonoids that help increase sweating.
