How To Make Aspirin from Willow
How To Make Aspirin from Willow
Willow bark contains a chemical active ingredient called salicin, which the body converts into salicylic acid (C7H6O3) — a pain reliever and anti-inflammatory agent that is the precursor to aspirin. In the 1920s, chemists learned how to extract salicylic acid from willow bark to reduce pain and fever. Later, the chemical was modified into the present form of aspirin, which is acetylsalicylic acid.
While you can prepare acetylsalicylic acid, it's also nice to know how to get the plant-derived chemical directly from willow bark. The process is extremely simple:
HOW TO GET SALICIN FROM WILLOW BARK
- Cut through both the inner and outer bark of the tree. Most people advise cutting a square into the trunk. Don't cut a ring around the trunk of the tree, as this can damage or kill the plant. Don't take bark from the same tree more than once a year.
- Pry the bark from the tree.
- Shred the pink section of the bark and wrap it in a coffee filter. The filter will help keep dirt and debris from getting into your preparation.
- Boil 1-2 teaspoons of fresh or dried bark per 8 ounces of water for 10-15 minutes.
- Remove the mixture from heat and allow it to steep for 30 minutes. A typical maximum dose is 3-4 cups per day.
Willow bark may also be made into a tincture (1:5 ratio in 30% alcohol) and is available in powdered form containing a standardized quantity of salicin,
COMPARISON TO ASPIRIN
Salicin in willow bark is related to acetylsalicylic acid (aspirin), but it is not chemically identical. Also, there are additional biologically active molecules in willow bark which may have therapeutic effects. Willow contains polyphenols or flavonoids that have anti-inflammatory effects. Willow also contains tannins. Willow acts more slowly as a pain-reliever than aspirin, but its effects last longer.
Since it is a salicylate, salicin in willow bark should be avoided by persons with a sensitivity to other salicylates and may carry a similar risk of causes Reye syndrome as aspirin. Willow may not be safe for persons with clotting disorders, kidney disease, or ulcers.
It interacts with several medications and should only be used as approved by a healthcare provider.
