This is a fascinating climbing succulent to me and I'm experimenting with eating it!
Cissus Quadrangularis has been used since ancient times and is one the most used medicinal plants in Thailand and throughout the Middle east and Asia. It is used, and has been used for centuries in India to promote muscle and bone development and healing. It is said to help torn tendons and broken bones heal up to 50% faster, and is also said to be hugely instrumental in battling obesity and weight loss. Its fast growing and a climbing succulent...
(being new, I accidently ended up in this forum and didn't even know what it was about until looking more, so I was in kind of the right place in one way and didn't know it. I had copied and pasted without editing something I had posted on craigslist about selling Cissus, and thought I was just sending the plant picture and info about the plant to the Succulents forum. I have since edited that post to delete the "for sale" part, yet have realized that someone in this forum may be interested, and if so, feel free to contact me.
Thank you, Happy Gardening, and anyway,... Its well worth researching more!
