The Tibetan medical work, fully titled Jiyao Guangzhu.Ciyi Yueguang, is a commentary on the ancient Indian medical text Ashtanga Hridaya.

Ashtanga Hridaya is a significant work of Ayurvedic medicine by the Indian physician Vagbhata, whose Sanskrit name is also known as Nagarjuna, also referred to as Ashvaghosha, an Indian philosopher around the 2nd century AD. In the field of medicine, he compiled the essence of ancient Vedic medicine and authored works such as Ashtanga Hridaya, and also wrote a self-commentary Ashtanga Hridaya Self-Commentary. In the 8th century AD, the Kashmiri scholar Dawalagawa (Candranandana) annotated Ashtanga Hridaya, creating his commentary Jiyao Guangzhu.Ciyi Yueguang, abbreviated as Yueguang. These two works were introduced to Tibet by the Tibetan philosopher and physician Rinchen Zangpo around the 11th century and were fully translated into Tibetan medical texts. During the translation into Tibetan, Rinchen Zangpo added some annotations and elaborations, making them Tibetan medical works. The eight branches of Tibetan medicine include general diseases, children's diseases, women's diseases, demonic diseases, trauma, poisoning, rejuvenation, and virility. These translations have had a significant impact on Tibetan medicine, and some contents were later incorporated by Yuthog Yonten Gonpo in the revision of Sibu Yidian.
