All I know is, this plant is probably common in South East Asia, and may be thought to have medicinal value.

Would like to know genus and species or common names.

Thanks!

I have read and it has been suggested that some people who have recieved organ transplants have aquired personality traits of their donors.
As a heart transplant recipient I must say I have experienced no such phenomenon myself. However I reserve judgement until I am satified personally that the existing informationm on the subject confirms or refutes claims that cellular memory exists.
I invite anybody who has direct or indirect knowledge of a donor organ that was transplanted and changed the personality of the recipient.
