Plandu / Onion (Allium Cepa)

Ayurvedic medicine is an old Indian science. Ayurveda offers the most effective natural treatment for illnesses and their cures. Every person has different symptoms and methods for investigating diseases. For example, we investigate patients using Trividh Pareeksha, which is darshan, sparsha, and prashan. We can also investigate diseases by using Nidan panchak, which includes nidana, poorva roopa, roopa, upshaya, and samprapti. Finally, we can understand the patient's condition using Prakriti, Vikriti, Sara, samhana, praman, Satmaya, satwa, ahar shakti, vyayan shakti, vaya, and bala. Ayurvedic medicine determines the ideal medication for the illness and provides easily accessible care. We'll talk about Allium cepa's numerous advantages for those in need as it is one of the most exquisite herbs referenced by Ayurvedic Acharyas in classical Ayurvedic scriptures.
