Thank you everyone for your helpful inputs on this thread! Actually I just saw them today.
My sister has been eating a lot of turmeric and in time, her doctor told her that she need not wear the stockings for DVT and she also stopped taking Warfarin so I thought all was ok. But then she became increasingly tired - and still she has been drinking all these sugary drinks. I guess the cause of the disease has not really been addressed so it came back.
Two days ago, she got a pulmonary embollism (blood clot went to her lung/s) and now she is in the hospital taking all sorts of tests. Doctor is inclined to prescribe surgery in the US (oh no) and she does not have a visa to get there. She is back on Warfarin once again.
Anyway, I will share all of the info here to her in the hopes she tries natural methods.
