Left?Plant to help us naturally

No saints power.
Recently, after a word or two, We start going crazy over a certain type of leaf/plant/ whatever that falls down the tree and inside that leaf/plant is a certain type of white seed that you bite into pieces and swallow down just like a sweet, only this is very bitter and the lingering taste will stay inside your mouth for at least half an hour.

So we been plucking going around the garden nearby our estates for possible alive of this leaf/plant.
And been peeling it constantly for the last 2-3 days in 156 for preparation for consumption.
Everybody has taken it once upon a time before.
But it it said it was especially good overall generally for the well being of the health but in specific areas like High blood pressure, and blood clots. In testimony for those stroke patients or wheelchair people, some had recovered after consuming it.
3 seeds twice a day!

I haven gotten the English name of the plant/leaf or the tree.
