What does sapang tree can cure?

I was told it cures fatigue when you see your veins gets inflamed and when you have visibly displayed veins coming out in your hands and feet, you have "pasma" or fatigue from using your computer keyboard or when washing your hands and feet when tired.

You then need to drink the red colored water coming from boiling 3 barks of sapang. I bought mine in Quiapo for 3pcs of the sapang bark for P20
