Yes, you don't need UV light. I should make that clearer in the tech. It's as plain as day with the naked eye which later is the DMSO and which is the garbage to remove. Elemi oil is slightly yellowish. DMSO is clear. After mixing them thoroughly and letting it sit for a few seconds they separate completely. The DMSO is the bottom layer and it's totally clear (unless you shine a UV light at it and then it becomes greenish blue). The junk layer to remove is the top layer, and it's slightly yellowish, the color of Elemi oil. Apparently the colored compound present in Elemi oil isn't soluble in DMSO. Actually most of the compounds in Elemi oil are not soluble in DMSO. Luckily the elemicin is. So anyway, after mixing you discard the top yellowish layer and keep the bottom clear layer.

If you wanted, instead of discarding the top yellowish layer, you could always keep it and use it separately as a sedative. It's a nice sedative. SWIM just doesn't like it mixed with elemicin. The sedative totally ruins the elemicin experience.

I'll add some pics to this tech later. A picture is worth a thousand words, as they say, and a few would make the tech much easier to follow.
