  • Pregnant and Nursing Women: Due to limited safety data, it is advisable to consult a healthcare provider before use.
  • Individuals with Liver Disease: Should use usnea with caution and under medical supervision because of potential liver toxicity.
  • People with Allergies: Those allergic to lichens or similar plants should avoid usnea.

Usage Guidelines

Usnea can be used both short-term and long-term, depending on the condition being treated. For acute infections or respiratory issues, it is typically used for a short duration until symptoms improve. For ongoing immune support or skin conditions, longer-term use may be appropriate but always under the guidance of a healthcare professional. Always consult with a healthcare provider to determine the correct dosage and duration for your specific needs.
