Soursop

Hi!
I am just trying to find out if soursop leaves contain vitamin K? If so, how much?
I sent some to my uncle who has cancer and liver problems, but the nurse told his wife that 'most leaves contain a lot of vitamin k so that's not good for his liver."
So I was just wondering if that is the same for soursop leaves??
I need to know these answers asap!
I know soursop is amazing for you!

Any one in india requires Guyabano (soursop) ganoderma, shiitake , bourdock or othe cancer and rare herbs may contact at alchemistjk at gmail dot com and may all at 91-9334851224
