Willows grow in abundance in northwestern, BC, Canada. I loved using them for decorations, creating wreaths, baskets and the biggest project of all was a massive gazebo for Dead Wood Gone Airbnb.
I used the bark for its medicinal property in the form of tea. Willow bark contains a chemical called salicin, which is similar to aspirin and flavonoids, which are anti-inflammatory plant compounds. Salicin is the precursor of salicylic acid. A phenolic chemical that has antibiotic and antifungal properties, which can help protect against infection.
I found it useful for headaches and muscle pain. People also use it for lower back pain, menstral cramps, osteoarthritis, bursitis, fever and flu.
You can use any number of different species of willow. Some have a strong woody flavor. Weeping willow is believed to be milder and there are some that have a minty smell which may be cooling and anti-inflammatory.
You can harvest willow bark any time of year, but the highest concentration of salicin is in mid-March, before the leaves emerge and while the sap is flowing.
You can store dried bark in an airtight container and keep in a cool place.
Warning: Willow bark may be safe to use for up to 12 weeks, but it can cause side effects such as diarrhea, heartburn, vomiting, itching, rash, and allergic reactions. It may also interact with medications that slow blood clotting, aspirin, choline magnesium trisalicylate, salsalate, and acetazolamide. If you have a medical condition and are taking medication, you should consult your physician before trying.
