Patanjali Giloy juice is an Ayurvedic herbal preparation made from the extracts of the Giloy plant (Tinospora cordifolia). It is known for its immune-boosting properties and is used to treat a variety of health conditions. The juice is made using a traditional Ayurvedic process that involves boiling and drying the Giloy stem, then grinding it into a fine powder. This powder is then mixed with water to make a juice.
