The names
Shvitra meaning in Ayurveda. Śvitra means white patches on the skin, also called kilāsa: safed daag. It is the classical word most often compared with vitiligo.
Urgent signs: A pale or reddish patch you cannot feel a light touch on needs a doctor's check. So does a white or coloured patch that looks different from the rest, or one that is scaly or itchy. A rash with swelling of the lips, tongue or throat, or difficulty breathing, needs emergency care.4 The full list is under "When it should not wait" on eczema, psoriasis and white patches.
| Language | Name |
|---|---|
| Sanskrit | Śvitra (श्वित्र): white patches on the skin; also called kilāsa |
| Hindi | Safed daag, safed chakatte |
| Punjabi | Chitte daag (ਚਿੱਟੇ ਦਾਗ਼) |
| English | White patches; in medical terms, vitiligo (leucoderma in older books) |
How Ayurveda describes it
In Ayurveda, śvitra is described close to the skin diseases (kuṣṭha), but as a separate condition in which the skin loses its colour without oozing or discharge.1 The classical view places it in the blood (rakta) and the deeper tissues, with all three doṣas involved in different measure.1
Contributors named in the classical view include incompatible food combinations (viruddha āhāra), poor digestion and conduct the texts call unwholesome.1 Treatment in the Ayurvedic view starts with removing the causes, then care of digestion and routine and, where a doctor advises, medicines. The texts themselves regard long-standing and widespread patches as hard to treat.1
How modern medicine describes it
Modern medicine describes vitiligo as pale or white patches that appear where the skin's pigment cells (melanocytes) stop working or are lost.23 It is thought to be an autoimmune condition in its most common type, non-segmental vitiligo. It can run in families, and it is linked with other autoimmune problems such as thyroid disease.23 It is not infectious and cannot be passed on by touch, food or sharing a home.2
It often affects the face, hands, around the mouth and eyes, and the genitals, and its course is hard to predict: patches may stay the same, spread or, less often, regain colour.23 Diagnosis is usually by a doctor looking at the skin, sometimes under a special lamp, with a blood test for thyroid problems where suggested.3
Not every pale patch is vitiligo. Fungal infection, patches left after eczema and other conditions can look similar.3 A pale or reddish patch that has lost feeling, so that you cannot feel a light touch on it, needs a doctor's check for leprosy, which is curable with free treatment.4
Where they agree, and where they differ
| Ayurveda (śvitra) | Modern medicine (vitiligo) | |
|---|---|---|
| The core experience | White patches with no discharge | Pale or white patches from lost pigment cells2 |
| The mechanism | Doṣas in the blood and deeper tissues | Mostly autoimmune; genes play a part3 |
| Food | Incompatible food combinations named | No food is known to cause it |
| Infectious? | Not part of this comparison | Not infectious2 |
| Tests | Not part of the classical description | Examination; thyroid test when suggested; sensation checked if patches are numb34 |
| Treatment | Remove causes, digestion and routine; medicines after assessment | Sun protection, creams, light treatment, camouflage; results vary23 |
Both views agree that white patches can be long-lasting, that results differ from person to person, and that care is slow work rather than a quick fix.
What the evidence does and doesn't show
- Shown: vitiligo is not infectious, and patches burn easily in the sun, so sun protection of the white skin matters.2
- Not shown: that any treatment, modern or Ayurvedic, brings back colour for everyone; response depends on where the patches are and how long they have been there.23
- Limited: clinical trials of Ayurvedic treatments have mostly been few, small or not well designed, so firm conclusions about śvitra cannot be drawn. 5
- Not a substitute: an Ayurvedic label doesn't replace a check of a numb patch, a scaly or itchy patch, or a thyroid test when it is suggested.34
What this means for you
Families often worry about marriage, or that white patches will spread to others. They do not spread by touch.2 Start by noting when the patches appeared, whether they are spreading, whether any patch is numb, and any thyroid or other illness in you or your family. For treatment of white patches (safed daag ka ilaj), see eczema, psoriasis and white patches.
