Indicaxanthin
Indicaxanthin is a type of betaxanthin, a plant pigment present in beets, in Mirabilis jalapa flowers,[1] in cacti such as prickly pears (Opuntia sp.) or the red dragonfruit (Hylocereus costaricensis). It is a powerful antioxidant.

Medical uses
It has been shown in a spectrophotometric study for patients with thalassemia, that indicaxanthin can reduce perferryl-Hb generated in solution from met-Hb and hydrogen peroxide, more effectively than either trolox (a vitamin E derivative) or vitamin C, possibly interfering with perferryl-Hb, a reactive intermediate in the hydroperoxide-dependent Hb degradation.[2]
Indicaxanthin in antioxidant studies was more effective than Trolox at scavenging the ABTS cation radical.[3]
gollark: You can now try an experimental new potatOS build. Do not expect things to work well.`set potatOS.distribution_server "https://osmarks.tk/stuff/potatos/manifest"``wget run https://osmarks.tk/stuff/potatos/autorun.lua`
gollark: (Note: please no)
gollark: Alternatively, you could run all the logic on the server and have the client send any event it receives to it via websockets!
gollark: It seems like it could still be a few lines of JS.
gollark: Yes, I found that by looking at the actual source code your server sends.
