Muchkund / Bayur Tree (Pterospermum Acerifolium)- Ayurvedic Properties, Effects On Doshas & Dosage


The knowledge of Ayurveda was passed by sages orally In India to their students in different places in the form of conferences or seminars. They have discussed every herb, every disease, and every milestone of the human. According to Ayurveda, every person is influenced by certain elements that are present on the earth in the form of Panchamahabhutas and tridoshas. Panchamahabhutas are space, air, fire, water, earth, and tridoshas are Vata, pitta, and Kapha. These all must be in a balanced state so our body is always set to keep away the diseases. Many persons have the Prakriti consisting of two doshas like vata-pitta or Kapha- pittaj which means these persons have both dosha properties. These Prakriti are influenced by our dietary habits and when it gets vitiated we can develop various diseases. In this article writing, we are going to discuss the one such herb that directly acts on our doshas and helps our body to maintain the balance between Prakriti and doshas.
