Will bhringrajasava increase blood sugar

For the past six months, my 68-year-old mother has been taking bhringrajasava everyday after lunch (20ml daily mixed with an equal quantity of water) and recently, she had blood tests for peripheral neuropathy, and the results showed that her blood sugar (FBS, ppbs) was slightly increased for the first time ever. The doctor concluded that this raised blood sugar was the cause of her neuropathy. My mother started using this syrup to prevent stomach/lever discomfort brought on by the TB treatment she was receiving at the time, which is now complete.  She is now taking a number of bp, sugar and neuropathy medications and in order to prevent stomach discomfort caused by taking all of these medications at once, as well as potential side effects, she has been using bhringrajasava 20ml everyday for the last month. The question I have here is if everyday bhringrajasava consuming would raise blood sugar? Which ayurveda medication is the finest and has no side effects to prevent stomach upset?
