I did an experiment with cold herbal compress!
I prepared for two small cloths. One soaked in peppermint decoction, another soaked in water.
Both cloths were squeezed and put on my arms for 2 minutes. After took out the cloths, I felt the arm put on decoction was warmer.
Is it the effect of peppermint? I didn’t check the temperature with thermometer, it’s just my feeling. Interesting!
Next time, I will try hot herbal compress with chamomile tea or rosemary tea for stiff shoulders!
