Venous ulcers are wounds that are thought to occur due to improper functioning of venous valves, usually of the legs (hence leg ulcers). They are the major occurrence of chronic wounds, occurring in 70% to 90% of leg ulcer cases. In Ayurveda, this condition is considered as duṣṭa vraṇa. It can be managed with the specific s'odhana therapy.
A venous leg ulcer is the wound occur due to chronic venous insufficiency. It is due to improper function of venous valves of the leg around 70 to 90% of chronic leg 
ulcer is of venous origin. If this ulcer left untreated or not
properly treated, they can lead to cellulitis, gangrene and
even amputation of the affected limb. Recurrence is very
common in 54 to 78% cases by the fifth year of healing.
The overall incident rate in male is 0.76% and1.42% in the
female population.
It occurs due to raised intravenous pressure secondary
to deep vein thrombosis (DVT), obesity, injury, chronic
constipation, and long-standing occupation. Chronic and
prolonged cases of varicose vein yield valve incompetent
resulting in venous hypertension allowing blood protein
fibrinogen leakage causing fibrin to build up around
vessels preventing oxygen and nutrients from reaching
the cells. This fibrin plug causes ischemia resulting in
delayed healing of wounds. Continuous venous hyper-
tension damages capillaries of skin and subcutaneous
tissues, resulting in capillary proliferation and inflamma-
tion and progress in venous ulceration.
In conventional
systems, supportive care such as wound dressing, elastic
bandages, and compression stocking, self-care include leg
elevation, and physical exercise is being used apart from
medications like antibiotics, dietary supplements, and
non-steroidal anti-inflammatory drugs. Surgical treat-
ment includes skin grafting, sclerotherapy, Laser ablation,
correction of the venous plexus through reconstructive
surgery is practiced which have their limitations.
In
Ayurveda, this condition is clinically correlated with ‘Sira
janya dushta Vrana’. Dushta Vrana is a non-healing/delayed
healing type of wound resulted from varied etiology.
Ayurvedic medicines have shown its efficacy in many
chronic and challenging disorders. There are numerous
formulations in Ayurveda to treat skin ailments and
various types of ulcers

Graying of hair is generally considered a sign of old age. At times, graying starts even at a young age. Modern lifestyle with poor eating habits and erratic lifestyle have caused young people to go gray. Stress is one of the top contributors to the premature graying of hair
A venous leg ulcer is the wound occur due to chronic venous insufficiency. It is due to improper function of venous valves of the leg around 70 to 90% of chronic leg Nutritional deficiencies are among the causes of greying hair. Therefore, it is important to ensure that you eat healthy to prevents grays and promote hair growth. Hair also starts to go gray due to a drop in the production of the dark pigment – melanin in the hair roots.
Certain health problems can also lead to the greying of hair. For example, disorders like thyroid issues and anemia can cause hair to become prematurely gray. Those who suffer from ailments of the stomach like mal absorption are also prone to greys. Diseases affecting the small intestine like celiac disease, Crohn’s disease, tapeworms and other gut-related problems can be linked to greying of hair.
Ayurveda and Graying Hair
In Ayurveda, this condition is called palitya or akala palitya (premature graying of hair).
According to Ayurveda, greying hair is a pure Pitta disorder that occurs due to the vitiation of Pitta dosha (biohumor related to Fire and Water). This is why people of the Pitta constitution tend to start graying earlier than others. Excessive Pitta in the sebaceous glands which reside at the hair roots, called folliculitis can also result in hair loss and graying prematurely.
Pitta-provoking habits such as excessive passion, anger and physical strain results in graying of hair. One must also avoid Pitta-genic beverages like alcohol, tea and coffee. Intake of spicy, oily, salty and sour, fermented foods along with meat can aggravate Pitta.
But apart from being a primarily Pitta problem, the sage Vagbhata classified palitya according to the doshic dominancy.
Vata dosha: Hairs develop split ends; brittle, dry and rough in texture; color appears shimmery and transparent like water
Pitta dosha: Scalp shows signs of burning; hairs have a yellowish tinge
Kapha dosha: Hairs are thick, long and exceptionally white in color
Symptoms of Graying Hair
The regions just above the ears and at the temples are the first to show signs of grays. This graying may start to spread to the sides and the top of the scalp. In men, the facial hair like the beard and mustache begin graying sooner while the hairs on the chest and pubic area follow later. If you’d like to identify whether you are graying earlier than usual, take note of the following graying hair symptoms.
(LPP) is dyschromia of unknown etiology described clinically as hyperpigmented gray-blue or brown-black macules or patches in a photodistributed pattern. Since its discovery, LPP has often been reported in variety of ages predominantly in dark skinned ethnicities. LPP lesions exhibit a range of pigmentary dyschromia, from brown-blackish to blue or purple-grey macules or patches.1 Areas of involvement tend to be asymptomatic, but pruritus/ or burning may be present. There are several treatment options that have been reported with variable efficacy for improvement of the appearance of the lesions, but due to the chronicity of the underlying disease , none of these treatments are found curative. Ayurvedic medicines emerge here as possible intervention in chronic and lifestyle disorders in absence of a real cure.2 Skin diseases are collectively described as kushtha roga in Ayurveda.3 Due to its resemblance in signs and symptoms, LPP seems similar to charma kushtha, which is a vata and kapha dosha dominant condition in class of kshudra kushtha . 4 The vitiated dosha affects the skin and its blood circulation affecting the moisture of the tissue . Affected skin therefore becomes discoloured and thick.
Vitiligo is a progressive, idiopathic, pigmentation disorder of the skin, characterized by hypopigmented white lesions. PUVA therapy is the treatment of choice in the modern system of medicine. In Ayurveda, Shvitra or Kilasa is the term employed to describe hypopigmentation disorders of the skin. Shvitra is caused by various dietic and behavioral factors which aggravate the tridoshas, especially the Kapha dosha vitiating the Meda dhatu. Many Ayurvedic drugs are well known for the regeneration of melanocytes, among which Bakuchi is one. Vitiligo (leukoderma) is a pigmentation disorder with complex causes. Depigmented patches appear on the skin, hair, mucous membranes and the retina. It can begin at any age, but in about 50% of the patients, it starts before the age of 20.[1] The emergence of white patches can be brought on by a variety of impulses. Many people report that their vitiligo first appeared following a stressful event, such as an accident, job loss, death of a family member, severe sunburn, or serious illness. It is sometimes associated with and is secondary to hypothyroidism, diabetes mellitus, and pernicious anemia.
There are mainly three theories about the underlying mechanism of vitiligo, which are as follows: (i) the first theory states that nerve endings in the skin release a chemical that is toxic to the melanocytes; (ii) the second theory states that the melanocytes simply self-destruct; and (iii) the third theory is that vitiligo is a type of autoimmune disease in which the immune system targets the body's own cells and tissues
Oral and topical psoralens have both been used with varying results in the treatment of vitiligo. Psoralea corylifolia (Bakuchi) is a renowned herb and is a rich source of naturally occurring psoralen. It sensitizes human skin to the tanning effect of UV and sunlight. Autoimmune destruction is one of the major causes of destruction of melanocytes.
Shwitra or Shwet-Kushtha can be co-related with skin disease "vitiligo" in biomedicine. According to Ayurveda, the skin is one of the essential sense organs. Vata and bhrajaka pitta reside in the skin (called twak in Sanskrit). As the skin covers the whole body, bhrajaka pitta should be maintained in a proper state, and it needs continuous care. An imbalance in Vata and bhrajaka pitta may cause skin diseases. The first step (Step 1) in Ayurvedic management of vitiligo is purification therapies (shodhana karma) using herbal decoction of Psoralea corylifolia (bakuchi kwatha) and Euphorbia neriifolia (snuhi) aimed to induce multiple bouts of purgation. In the next step (Step 2), oil massage using oil selected on the basis of patient examination (rogi pariksa) and disease (roga). Step 3 is the exposure of lesions to the sun rays as long as the patient can tolerate (Soorya pada santhapam in Ayurveda). Herbomineral preparations include topical application of herbal Lepa, powders made up of medicinal plants (Curna), herbalized ghee preparations similar to paste (Ghrita, semi-solid preparations taken orally, by licking (Avaleha), herbalized oil preparations (Thaila), fermented solutions (Asava-Arista), and tablets (Vati/Gutika).
