Novel Herbal Composition for Treatment of Psoriasis and Other Skin Disorders

Description

FIELD OF THE INVENTION

The present invention relates to a herbal composition useful in treatment of psoriasis. More particularly, the invention relates to a composition comprising extracts of Psoralia corylifolia seeds and/or Luffa acutangula seeds and/or Rubia cordifolia roots and/or Boswellia serrata gum resins and/or Brassica nigra seeds and oils of Azadirachta indica seeds and/or Linum usitatissimum seeds and/or Vitis vinifera seeds and/or Brassica nigra seeds and/or Pongamia seeds and a cosmeceutically acceptable carrier, methods of obtaining the same, cosmeceutical formulations thereof and methods of using the composition for treatment of psoriasis, a chronic and non-contagious auto-immune disease that affects the skin and joints and other related skin disorders in humans.

BACKGROUND OF THE INVENTION

Psoriasis is a chronic, non-contagious autoimmune disease that affects the skin and joints. It commonly causes red, scaly patches on the skin. The scaly patches caused by psoriasis are called psoriatic plaques. The skin accumulates rapidly at these sites and becomes silvery-white in appearance. Plaques occur frequently on the skin of the elbows and knees but can affect any area including the scalp and genitals. In contrast to eczema, psoriasis is more likely to be found on the extensor aspect of the joints.

This disorder is a chronic recurring condition that varies in severity from minor localized patches to complete body coverage. Generally fingernails and toenails are affected by the infection (psoriatic nail dystrophy) and can be seen as an isolated finding. Psoriasis can also cause inflammation of the joints, which is known as psoriatic arthritis. Ten to fifteen percent of the total people with psoriasis have psoriatic arthritis.

Psoriasis is the most prevalent autoimmune disease in the U.S. According to the National Institutes of Health (NIH), as many as 7.5 million Americans—approximately 2.2 percent of the population—have psoriasis. 125 million people worldwide—2 to 3 percent of the total population has psoriasis. Studies have shown that between 10 and 30 percent of people with psoriasis also develop psoriatic arthritis. Psoriasis prevalence in African Americans is 1.3 percent compared to 2.5 percent of Caucasians.

The direct and indirect health care costs of psoriasis for patients are calculated at $11.25 billion annually with work loss accounting for 40 percent of the cost burden. Approximately 60 percent of psoriasis patients missed an average of 26 days of work a year due to their illness.

The treatment for psoriasis is mainly topical application, phototherapy and systemic administration of antibiotics, as pills or injections in case of severe psoriasis and psoriatic arthritis. There are many medications and synthetic drugs available for psoriasis. FDA has approved three new treatment options for psoriasis patients such as Taclonex Scalp, a new topical ointment for treating scalp psoriasis, Xtrac velocity excimer laser system, which emits a high-intensity beam of ultraviolet light that can treat moderate to severe psoriasis and a drug molecule adalimumab approved to treat moderate to severe psoriasis. Adalimumab had already been approved to treat psoriatic arthritis. Over times, psoriasis can become resistant to a specific therapy. Treatments may be periodically changed to prevent resistance developing (tachyphylaxis) and to reduce the chance of occurring adverse reactions.

It is therefore very important to develop safe and effective medications for psoriasis and other related skin disorders from natural sources. The present invention involves the identification of herbal extracts and oils in a unique combination that can be effectively formulated as topical application for treatment of psoriasis without any side affects.

OBJECT OF THE INVENTION

It is an object of the present invention to provide a herbal formulation for the treatment of psoriasis and other related skin disorders.

Another object of the invention is to obviate the disadvantages and side effects of the available treatment methods and compositions.

Still another object of this invention is to prepare a cosmeceutical composition from the said herbal extracts and methods of preparing the composition for human skin disorders.

Yet another object of this invention is to provide a method of preparation of a herbal formulation for the treatment of psoriasis and other related skin disorders.

SUMMARY OF THE INVENTION

Pharmacological Screening of the Extracts and Oils for Topical Anti-Psoriatic Activity by Mouse Tail Test

The composite extracts, oils blends and individual alcohol extracts were subjected to screening for evaluation of Anti-psoriatic activity by Mouse tail test and the results are summarized as FIG. 1-4.

Clinical Study to Evaluate Safety and Efficacy of Antipsoriasis Cream

An open clinical study was conducted to evaluate the efficacy and safety of Antipsoriasis cream in patients suffering from mild to moderate psoriasis. The study was conducted at Zawar's Dermatology Clinic, 21, Shreeram Sankul, Opposite Hotel Panchavati, Vakilwadi, Nashik, India

Ten patients of both sexes, aged more than 18 years, who were clinically diagnosed as suffering from mild to moderate Psoriasis with erythema (redness), induration (thickness) and desquamation dry silvery scaling. Informed consent were obtained from the patients who were willing to take part in the study and enrolled on the study. Patients with any systemic illness or those patients who are not willing to follow the requirements of the study were not included in the study. The subjects who have qualified the screening and willing to participate in the study were called for the study, All the subjects were given antipsoriasis cream to be applied twice daily on the affected areas for a period of 3 months.

The evaluation for the clinical parameters was done at the beginning and at the end of every month for 3 months of the study. The clinical parameters of Psoriasis evaluated are PASI score, erythema (redness), induration (thickness) and desquamation (scaling) Auspitz sign. Severity parameters were measured on a scale of 0 to 4, from none to maximum.

Psoriasis Area Severity Index (PASI) is the widely used tool for the measurement of severity of psoriasis. PASI combines the assessment of the severity of lesions and the area affected into a single score in the range 0 (no disease) to 72 (maximal disease).

The body is divided into four sections head (H) (10% of a person's skin); arms (A) (20%); trunk (T) (30%); legs (L) (40%)). Each of these areas is scored by itself, and then the four scores are combined into the final PASI. For each section, the percent of area of skin involved, is estimated and then transformed into a grade from 0 to 6:

- 0% of involved area, grade: 0
- <10% of involved area, grade: 1
- 10-29% of involved area, grade: 2
- 30-49% of involved area, grade: 3
- 50-69% of involved area, grade: 4
- 70-89% of involved area, grade: 5
- 90-100% of involved area, grade: 6

Within each area, the severity is estimated by three clinical signs: erythema (redness), induration (thickness) and desquamation (scaling). Severity parameters are measured on a scale of 0 to 4, from none to maximum. The sum of all three severity parameters is then calculated for each section of skin, multiplied by the area score for that area and multiplied by weight of respective section (0.1 for head, 0.2 for arms, 0.3 for body and 0.4 for legs).

PASI=0.1×(E_H+I_H+D_H)×A_H+0.2×(E_A+I_A+D_A)×A_H+0.3×(E_T+I_T+D_T)×A_T+0.4×(E_L+I_L+D_L)×A_I

Where E-Erythema, I-Induration and D is desquamation and (head (H) (10% of a person's skin); arms (A) (20%); trunk (T) (30%); legs (L) (40%))

Auspitz sign—It is the appearance of punctuate bleeding spots when psoriasis scales are scrapped off. Auspitz sign occurs because the capillaries under the epidermis are numerous and twisted, very close to the surface. Auspitz sign is used as a diagnostic tool for psoriasis. The combination of inflamed, thickened skin with silvery scale and Auspitz sign however appears to be unique to psoriasis. It is measured in the severity scale from 3 (severity), to 0 (Normal), with moderate (1).

In addition at each visit all the cases were evaluated for efficacy and any adverse effects, vital examination and laboratory investigation. The changes in various parameters from baseline values and the values until the and of the study were evaluated by “Paired ‘t’ Test”.

The demographic details of the subjects at entry are listed in table. All the 10 enrolled completed the study and the data were available for analysis. Treatment with antipsoriasis cream showed improvement in various clinical parameters of psoriasis which includes erythema, induration, dry silvery plaques and Auspitz sign and PASI score. Improvement was significant in clinical symptoms such as erythema, induration and Auspitz sign score. There was also a improvement in dry silvery plaques and PASI score.

There were no clinically significant adverse reactions, either reported or observed, during the entire study period and overall compliance to the treatment was excellent. Significant symptomatic relief was observed with Antipsoriasis cream in patients presenting with mild to moderate psoriasis. There were no clinically significant adverse reactions, either reported or observed, during the entire study period and overall compliance to the treatment was excellent. Thus it can be concluded that Antipsoriasis cream is effective and safe in patients suffering from mild and moderate psoriasis, without any observable adverse effects.
