But it shows you how to pointlessly add unnecessary solvents to your extracts and kill off all your waxes and terpins so you can turn your nice yummy tasting wax into bland hash oil. But on the bright side, it might max your extracts slightly stronger. Because, you know, the biggest problem with BHO is that it's not strong enough.
Actually the point of isomerization is to change, or re-arrange, the structure of molecules in low grade material, with inactive forms of THC to the more active form of THC. It's a waste to do it with high quality material, but you can continuously isomerize into a more potent product. The US military experiments with isomerization in the 1950's and '60s, I believe they discovered 8 stereoisomers, 2 of which they claimed "did nothing", but rather, as we know now, modulate the other cannabinoids...
In short, Isomerizations turns your crap into non-crap, that you could eat or inject to get an effect. At one some point you can distill roughly 5x and only get a 2x as potent product.
The US military stopped experimentation because it was not economically viable as a weapon, and at one point they reached a dosage of roughly 55µg/KG (55/1,000,000 of a gram) of body weight, had effects for upwards of 30 hours and people, and got scared because it lowered heart rate so drastically...
