Smallpox corresponds to the Ayurvedic condition Masurika characterized by lentil shaped pustules covering the body. It is recognized as an Aupasargika or contagious disease spreading through contact and breath. The pathology involves the vitiation of Tridoshas and blood caused by improper diet and external agents known as Grahadosha. Clinical features include high fever burning sensation and eruptions which become fatal if they assume a coral color indicating deep tissue involvement. Ayurvedic management emphasizes blood purification and cooling therapies using herbs like Neem. Historically significant the World Health Organization declared the global eradication of Smallpox in 1980 marking it as the first disease successfully eliminated through human public health efforts.
Smallpox was a contagious, disfiguring, and often deadly viral disease. In Ayurveda, this condition is known as Masurika. It is characterized by the eruption of pustules (boils) all over the body that resemble lentils (Masura). Ayurvedic texts describe it as a severe disease involving the vitiation of all three Doshas (Vata, Pitta, and Kapha) and the contamination of blood (Rakta), often leading to fatal complications if the pustules turn the color of coral or involve deep tissues.
Modern Definition: An eradicated infectious disease caused by the virus, characterized by fever and a progressive skin rash. is a disease where pustules () resembling (lentils) appear on the body, accompanied by fever () and burning sensation (). It is classified under (contagious diseases) that spread through contact and breath.
The causes are a mix of dietary indiscretions, environmental factors, and contagion.
Madhava Nidana classifies Masurika into five types based on the dominant Dosha:
The treatment principle follows the management of Kushtha (skin diseases) and Visarpa (erysipelas/herpes).

Q: Is Masurika contagious?
A: Yes. Ayurveda classifies Masurika as an Aupasargika Roga (contagious disease). It spreads through physical contact (Gatrasamsparsha) and sharing breath/being in close proximity (Nishvasat).
Q: Why is it called "Masurika"?
A: It is named after the lentil (Masura or Masoor Dal) because the pustules or boils that appear on the skin resemble the shape and often the color of lentils.
Q: What diet is best during this disease?
A: A diet that pacifies Pitta and Kapha is recommended. This includes light foods, bitter vegetables like Neem and Patola (pointed gourd), and avoiding salt, sourness, and heavy oils.
Q: Does Ayurveda differentiate between Smallpox and Chickenpox?
A: Yes. While the classical term Masurika historically covered Smallpox, modern Ayurvedic practitioners and texts often use the term Laghu Masurika (Light Masurika) to describe Chickenpox, distinguishing it from the more severe forms.
