Human skin acts as a barrier between the interior body and exterior environment maintaining a controlled dynamic equilibrium. Stresses imposed by the environment and various human factors such as exposure to sunlight, genetics, eating habits, lifestyle, etc., can cause undesired changes in the skin, thus incurring a skin disease or disorder. Major purpose of cream under consideration is to help reverse these changes and maintain healthy, normal skin. Generally, the most common skin diseases and disorders include Eczema, Psoriasis, burn wounds, Shingles, scaring of skin to form keloids, discoloration or Vitiligo, Lipoma, dry skin, skin allergies, contact dermatitis and cracked heels, etc. These are observed in individuals at various ages.
Eczema is a prevalent skin disorder, encompassing a variety of diseases such as contact dermatitis and dyshidrotic. Eczema is characterized by initial symptoms of blistering and dry cracked skin on the hands or feet, affecting the tips and sides of fingers, toes, soles and palms. The disease develops progressively into continual scaling, peeling, cracked skin, bleeding, deep fissures and open wounds. These conditions cause the skin to become red, itchy and inflamed. There are several types of eczema: atopic dermatitis, contact dermatitis, dyshidrotic eczema, nummular eczema, seborrheic dermatitis and stasis dermatitis. Living with eczema can be an ongoing challenge. It is most common for babies and children to develop eczema on their face (especially the cheeks and chin), but it can appear anywhere on the body. Usually eczema goes away as a child grows older, though some children will continue to experience eczema into adulthood. Adults can develop eczema, too, even if they never had it as a child. Eczema is usually itchy and might develop extremely inflamed skin. The most common treatment includes Eczema phototherapy or light therapy, an eczema treatment that uses ultraviolet light to reduce skin inflammation. The biggest drawback of eczema light therapy is that it is very time consuming and requires many trips to the doctor's office over several weeks. Although there are light therapy units available by prescription to use at home, most dermatologists prefer treatments done in the office where UV light exposure can be controlled. Additionally, the Eczema light therapy may cause burning, headache and nausea, skin damage, and even skin cancer. Another common treatment is prescription topical medication and/or over-the-counter (OTC) remedies, for instance, the use of Cortisone steroid creams. This type of treatment is easy to use, works fast, and costs less than many other treatments. However, the steroid cream treatment normally reduces the symptoms such as itchiness temporarily. As soon the treatment stops, Eczema may come back and becomes even worse than before the treatment. Further, this type of treatment may cause addition and tolerance to the steroid chemicals, and side effects such as skin thinning and degrading, bruising, toxin build-up in the body, and hormone suppression, etc.
Psoriasis is a common skin condition that speeds up the life cycle of skin cells. It causes cells to build up rapidly on the surface of the skin. The extra skin cells form scales and red patches that are itchy and sometimes painful. Psoriasis is a chronic disease that often comes and goes. The main goal of treatment is to stop the skin cells from growing so quickly. Psoriasis signs and symptoms are different for everyone. Common signs and symptoms include:
Herpes Zoster, also called Shingles or Acute Posterior Ganglionitis, is infection that results when varicella-zoster virus reactivates from its latent state in a posterior dorsal root ganglion. Symptoms usually begin with pain along the affected site, followed by a rash, usually crop of vesicles on an erythematous base and forming small blisters filled with a serous exudate, as the fever and general malaise continue. The painful vesicles eventually become cloudy or darkened as they are filled with blood, and crust over within seven to ten days; usually the crusts fall off and the skin heals, but sometimes, after severe blistering, scarring and discolored skin remain. The rash is accompanied by severe pain, which, in some people, does not subside after healing but persists for months or years. This prolonged zoster associated pain, usually defined as pain persisting for more than four months after the rash has healed, is known as postherpetic neuralgia and is the most common complication of herpes zoster. The pain can be debilitating, exacerbated by the slightest touch, and lead to loss of employment, depression, and social isolation. There is no cure for Shingles, but prompt treatment with prescription antiviral drugs can speed healing and reduce the risk of complications. However, many antiviral medications can cause side effects such as nausea, headache, rash, diarrhea, etc.
Burn wounds: The skin's three anatomic layers, i.e., epidermis, dermis, and subcutaneous tissue, have functions that are lost after burn injuries. The epidermis is a barrier to bacteria and moisture loss. After a burn injury, local wound care and fluid management are required. The dermis provides elasticity and protection from mechanical trauma, and it contains blood vessels that supply all skin layers. When the skin is damaged, epidermal cells regenerate from cells deep within the dermal appendages, which is why deep dermal injury causes significant scarring and permanent skin damage. Most patients with burn wounds are treated in the outpatient setting, making primary care physicians the main treatment source for thousands of burn patients each year. Superficial (first-degree) burns involve only the epidermis; like a sunburn, they are erythematous, painful, and dry. They are most often the result of severe ultraviolet exposure or minor thermal injury. The most common treatment for skin burns is using creams or lotions such as aloe vera gel, calendula tincture, honey, etc. Many of these creams or lotions have problems that affect the effectiveness, including too little effective ingredient in the formulation, color and/or cosmetic additives, etc.
Lipoma: Lipoma is a benign growth of fatty tissue that slowly develops under the skin. Lipomatous tumors are a common group of mesenchymal lesions. The lipoma is only painful if it grows into nerves underneath the skin. Usually lipomas are not painful, but sometimes can have extra blood vessels mixed in that can be associated with some pain or tenderness. Some lipomas grow noticeably causing concerns. Dermatologist can treat the lump if it bothers the patient. The most common way to treat a lipoma is to remove it through surgery. This is especially helpful if the patient has a large skin tumor that is still growing. However, surgery brings the risk of recurrence, pain, scar, tiny nerve injuries, infection, etc.
Keloids: Keloids are incredibly common in some patient populations. These abnormal scars, which grow well beyond the border of the original injury site, are typically unsightly, inconvenient, and often uncomfortable. Keloids cause pain, pruritic, and even hyperesthesia, as well as social discomfort and embarrassment. Until recently, very little was known about the etiology of keloids, and even less was known about how to effectively treat and manage their growths. Surgical excision is frequently inadequate, because many, if not most, keloids recur after excision. Other treatment measures, including corticosteroid injection and the use of pressure dressings, were based on medical intuition and anecdotal evidence more than scientific research.
The objective of the present invention is to provide relief during these skin problems and obviates the drawbacks of the existing formulations and treatment methods for skin diseases and disorders. More specifically, the present invention provides a natural herbal formulation for therapeutic and cosmetic applications in conditions such as Psoriasis, Eczema affected skin, dry skin disorders, Lipoma, skin allergies, depigmentation or Vitiligo and anti-fungal activity, etc. The preferred embodiment of the formulation of the present invention includes castor seed oil, kokum seed extract, solanum nigrum (black nightshade) extract, Aloe Vera, Air Potato Extract and emulsifying agent.

The present invention further comprises a method for preparing an herbal cream or gel using any of the embodiments of the formulation of the present invention described above. The first step in the preparation of these formulations involves a process of making the plant extract of the Solanum Nigrum and Dioscorea bulbifera Linn suitable for incorporating into a cream or gel base. The appropriate portion of the plants are collected and dried in sunlight for at least 72 hours or until the material is dry. A specific amount of the Solanum Nigrum and Dioscorea bulbifera Linn material is then extracted with a solvent including, but not limited to, water-hexane, chloroform, ethanol, methanol, and water. The choice of solvent depends upon the type of material expected at the end of the extraction process. The extraction process and creation of the cream of the present invention is described in detail in TABLE II.
The formulations and method of the present invention are based on pharmacological scientific principles rather than literature describing common herbs that are good for the skin. While there are a number of herbal creams on the worldwide market available for the treatment of skin disorders, few contain the active ingredients as described in this invention. Moreover, it has been reported that many marketed herbal topical skin products, either don't work or they are misleading, claiming to be natural, but adulterated with potent steroids.
Because of the intensive study conducted by the inventors with the aim of achieving aforementioned objectives, new processes for the preparation of cream formulations for topical use were developed employing herbal drugs which are from natural origin, incorporating them into cream bases along with synthetic materials which are known to possess water retaining properties. Thus, the present invention provides an effective treatment of skin relief for psoriasis, eczema, burns, keloids, scars, contact dermatitis, lipoma, Shingles and dermatophyte fungi and an efficient method of making the formulations.
Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention.
The above formulation listed in Table II was tested for multiple cases of Psoriasis, Eczema, Lipoma, Shingles, Burn Wounds, Keloids and Scars for relief on human subjects of both sexes of different age groups in India during a period of 2 years.
The skin cracks in all cases were healed within 1 to 2 weeks when applied twice daily. Moderate skin problems and wounds were healed within 7 days and severe skin cracks were healed by continuous use of 1 to 2 months in case of Psoriasis and Eczema. The natural suppleness of the skin was restored in all cases after healing. Few subjects reported healing of even leprosy wounds on hands, fingers and toes. Several subjects with severe case of Psoriasis reported total healing of skin on both hands after continuous use of 1 to 2 months. Multiple cases also reported immediate relief from Shingles pain. In all the subjects, soothing effect was observed after one or two applications and new rejuvenated skin was formed in matter of days.
The above observations ascertain that formulation described in Table II above is best for various types of skin diseases, rash, skin allergies and other skin problems in all cases.
The main advantages of the present invention are:
