i use this to help me relax before bed [SEP] i use this with lavender oil in my baths at night it relaxes my body and helps sooth sore muscles from exercising the flakes dissolve pretty quickly if you add it when you first start running the water it is mostly dissolved by the time you get inyou use cups of salt per bath so i expect this bag to last for a few baths there is no scent to this which i love because i can add my own essential oils to my bath if i want it scented
