Viruses, head traumas, and other events can cause us to lose our sense of smell, a condition called anosmia. Scientific research has found that the sense of smell can be retrained by sniffing a collection of scents from different families of aromas. This is volume one of two sample packs meant to help you in this process. You can also use these sample packs to help train your nose to understand the scent families as listed below.
The idea is to sniff each sample for about 10 seconds. Do this twice a day for several weeks, then switch to Nose Training Sampler Two. Even if you don’t have anosmia, this is a great way to learn about scent families and train your nose to recognize them.
