Arka

Arka refers to the leaves of the Calotropis plant, known for their toxic properties. In ancient Indian mythology, these leaves are infamous for causing severe health issues when ingested. In the story of Upamanyu, a disciple of the sage Ayoda-Dhaumya, he consumed Arka leaves out of desperation while tending to the cows, resulting in the tragic loss of his eyesight. The incident serves as a cautionary tale about the dangers of ignorance and the importance of adhering to wisdom and guidance.
