Background

Vitiligo is an acquired pigmentary, asymptomatic,multi-factorial, polygenic disorder of skin, resulting in the loss of functional melanocytes.Іt is characterized by de-pigmented milky white macules of varying sizes and shapes.There are no other structural changes except loss of color[1].Vitiligo usually affects the skin,but it can develop anywhere externally on the body where there is pigment.Patches of hair can turn white.The affected skin lightens or may turn completely white[2].

Іt is a repugnant and odious ailment and a disease of great antiquity which has been described since ancient times [3].The first record of this disease dates back to the period of Aushoorgan in the history of Іranian medicine about 2,200 BC [4] followed by “Ebers Papyrus” (1,550 BC) which described two types of disease affecting the color of the skin out of them one was probably vitiligo[5].

Vitiligo does not cause any harm to physical health,but concerns about appearance and ethnic identity can lead to serious psychological, social, and emotional difficulties; significantly impacting quality of life and causing havocs with the social living of patients [6].Prevalence is almost uniform among the entire human population, affecting all the races equally; however, it is more noticeable in people with dark skin [7],because white patches of vitiligo (being nearly identical to normal white skin) are less prominent on white population [8, 9].Globally about 1% of people are affected by vitiligo [10] and 2-3% in some societies [11].Males and females can be equally affected [3].About half of the total patient are below the 20 years of age and most develop it before 40 years[3].

Treatment of vitiligo is often strenuous and demanding, both for the patient as well as the doctor.There are multiple regimes & modalities which have different goals to manage the vitiligo.Herbal medicines have been used since ancient times for the treatment of vitiligo.Now, people are also becoming conscious of the potency and side effects of conventional drugs as compared to herbal drugs.WHO is encouraging the traditional drugs because of its less side effects, low cost and easy availability [12].WHO has also been active in creating strategies, guidelines and standards for natural medicines [13].Hence, an attempt has been made through this review paper to discuss vitiligo and its management withUnani&herbal medicines.

Results&discussion

The word “vitiligo” has been derived from the Greek word “Vitelius” meaning “calf” as white spots of vitiligo resemble white patches on calf [14].Іt is a chronic disorder characterized by partial or complete loss of pigment producing melanocytes within the epidermis (Figure 1).The most propounded theories for the pathogenesis ofbaraṣ(vitiligo) are genetic predisposition [15-17], autoimmune theory [8],autocytotoxicity [18], neural factors [19], defective growth factor [20].Vitiligo can be categorized as per their distribution, pattern and extent of de-pigmentation.Vitiligo is divided mainly into two types viz.segmental vitiligo and non-segmental vitiligo (generalized) [21].Generally topical monotherapy is indicated for mild to moderate cases of vitiligo [22, 23].Current treatment options in modern medicine for vitiligo include medical, surgical and additional treatments [24,25].Medical treatment helps to arrest the spread of de-pigmentation by targeting the immune system [26, 27].These include topical steroid therapy, psoralen photochemotherapy (PUVA therapy),depigmentation by permanent melanocytotoxic agents.Іn stable vitiligo cases, re-pigmentation can be achieved by dermatosurgical techniques like autologous skin grafts, skin grafts using blisters,micropigmnetation (tatooing), and autologous melanocyte [28, 29].Additional therapies include sunscreen and cosmetic camouflage which can be used along with surgical and medical treatments[30].
