Arikeelaka is a concept described in Kashyapa Samhita, which is a classical Ayurvedic text. It is related to the study of pediatrics and discusses various aspects of child health and diseases, including growth and development. Arikeelaka refers to a specific condition or treatment related to children's health, especially concerning early childhood diseases and nutrition.
- Bhav Prakasha is another important Ayurvedic text, but it does not specifically focus on Arikeelaka.
- Ashtanga Hridaya is a classical text by Vagbhata, focusing on a comprehensive view of Ayurveda, but it does not deal with Arikeelaka.
- Harita Samhita is also an Ayurvedic text, but Arikeelaka is not part of its teachings.
Thus, the correct answer is (1) Kashyap Samhita.
