The moon cycle thing isn't really all that tricky to understand...and when you consider the effect the moon has on the ocean tides each day - well, we can see how impactful the moon actually is :)
It's just the simple "push & pull" of the moon cycles - push IN the alcohol on a new moon and pull OUT the herbal goodies on the full moon.
Since this action 'rolls' with the every-minute changing cycles, it is my understanding that as long as we're on the basic 'top of the roll' we're still in the right area of the 'push & pull' sequence.
Those that have tested this, say that a tincture 'tinctured perfectly' according to the moon cycles is about 15% stronger and more effective. BUT the typical herbalist uses a ratio of 4 parts alcohol to one part herbs (tinctured for only 2 weeks, sometimes less) - we use a ratio 2 to 1...so we're 25% stronger from the 'get go' than the typical herbalist - before we ever take the moon cycle into account.
There are "frequency & energy" considerations that are more 'out there', but that's the basics.
The more often you shake it, the stronger it will be; the longer you tincture it, the stronger it will be. There's no doubt in my mind that your tincture WILL be better than 95% of anything else on the market :)
Tincture ON!
