I have not been able to find the medical term "jagrī" in any source available to me. It occurs in verse 2.111c of the Kālacakra-tantra (so in all manuscripts). It is in the phrase: jagrī-plīhārṣa-rogān api jaṭhara-gatān. So it refers to either an organ or a disease found in the stomach area, along with plīha (i.e., plīhan, spleen) and arṣa (for arśas, hemorrhoids). I am seeking a source for it in any Sanskrit medical treatise, and hopefully its meaning.
