Good site about plant extracts. Apparently BHO would be called a "resinoid", and if you dissolve that in alcohol and evaporate then it's an absolute. I know some people already call winterized BHO an absolute, but you don't even have to cool it to be an absolute. I guess a lot of stuff isn't even soluble in alcohol at room temperature or under mild heating. So it's not Butane Honey Oil, it's Butane Resinoid, or BR. As they mention, the solvent should be removed under vacuum and reclaimed.
