The Bower Manuscript is known for being a valuable source on which one of the following subjects in ancient India ?

The Bower Manuscript, discovered in 1890 by Captain Hamilton Bower in Kucha (Eastern Turkestan), is one of the oldest surviving Indian manuscripts, dating back to the 4th or 5th century CE (Gupta period). It is written in Sanskrit using the Brahmi script on birch bark.

The manuscript is primarily a medical treatise consisting of seven distinct texts. The most significant part is the Navanitaka, which is a compendium of Ayurvedic recipes, formulas, and treatments. It covers various medical topics, including the medicinal properties of garlic, treatments for eye diseases, and various herbal preparations. Its discovery provided crucial evidence of the advanced state of Ayurveda in ancient India and its spread along the Silk Road. While ancient India made strides in mathematics and astronomy (e.g., works of Aryabhata), the Bower Manuscript is specifically dedicated to medicine.
