Aspirin is one of the oldest and safest medicines in the world.
I prefer pure aspirin powder, 1-3 scoops (110-330mg) periodically, dissolved into a small amount of hot water and taken after a collagen containing drink and with Vitamin K2 tincture.
It has a warming, calming, stabilizing effect for me. I feel a sort anti-inflammation, not a numbness, but a deep lack of anything resembling negative sensation. A deep sense of energy enhancement.
1/2 - Aspirin Powder.
I have a feeling that willow bark tincture is even better than pure aspirin, as it contains a balance of multiple compounds. Still have not tried it tho.
