I have used roots from fresh to 2+ yrs old with no difference in the beneficial effects.
I prefer coconut oil as a base....it is full of short and medium chain triglycerides and absorbs fast and easily into the skin...some other additives I have put in include emu oil....again, full of short and medium chain triglycerides, teatree oil, pure vitamin E oil, apricot kernel oil, jojoba oil and avocado oil....all compliment it well, but roots and coconut oil as a simple base works a treat.
One can add bee's wax to thicken it some so it will remain solid over 21*C, but generally it is not needed....I have used old dried roots and found they are as effective as fresh roots...also, I have used a balm/rub that was kept stored in the fridge over 12 months after making it and it is still good.
not only this, but a root infused rub works VERY WELL at stopping weeping wounds, be they gravel rash, surgical sutures or even on infected tattoo's...insect bites that give a swelling and rash like appearance seem to benefit from cannabis roots also...
Muscle cramps and diabetic shakes are helped ....diaper, heat and sweat rashes...and the rootpulp can be used in a poultice with great effect.
