Yes, use the cayenne powder or make your own tincture. If you want to make a tincture it takes at least 2 weeks for it to be ripe enough to harvest. BTW, the powder is hotter than the tincture, so be aware. :-) Good stuff.
Yeah, get the enema bucket. MUCH cleaner/easier.
Yes, you can Liver-Flush without high enemas. We like to do both just to get the toxins out faster. There may be more to it than that, but I think that's the bottom line.
