Is this REALLY gynura procumbens?

[Daintree]

Hello,
This plant was given to me as 'longevity spinach', gynura procumbens.
But, depending on the website I look at for these names, I get different plants.
This is not a vine.  It is sprawling, and weakly climbing if propped up.
The older stems are thick and tough, but I wouldn't quite call them 'woody', and purple with green spots.
The younger stems are five-sided, green and succulent.
The young leaves are serrated, but as the get older and larger they look more undulate.

I want to make sure of what it is before I start eating it...

Thanks!
Carolyn

Yes, you are correct.   Gynura procumbens is often mistakenly referred to as ashitaba, when in fact ashitaba is angelica keiskei kodzumi
