Arka (Calotropis procera)
Botanical: Calotropis procera| English: Arka (Madar, Aak)
Arka is a potent Ayurvedic Botanical for Inflammation and Pain. Arka, also known as Madar or Aak, is a hardy perennial shrub belonging to the Asclepiadaceae family. It exudes a milky white latex when injured and bears broad, fleshy leaves that thrive across India’s varied climates. Traditionally, practitioners use the dried stem bark in Ayurvedic formulations to address deep‑seated conditions such as Gulma and Kustha. In Ayurveda, Arka is regarded as a powerful Sodhana and Virecana agent that helps balance Vata.
