If you have completed and received certification in the Wilderness Herbal First Responder, the certification lasts two years. You can re-certify by attending the last three days of the 2020 WHFR course in San Antonio, TX.
This will be heavy in hands-on training, scenarios and review and practice of skills you have learned with our school!
Unless you are using field first aid on a regular basis, it can be a perishable skill. Keep on top of your wilderness medicine skills with a refresher course.
