Chic bracelets that use acupressure to provide fast, natural relief from nausea and vomiting in as little as five minutes. Easing chemo, post-chemo, and post-surgery nausea. Wear during chemo infusion itself to help ward off nausea, and during recovery. Blisslets can be put on before or after nausea starts. First off, we love anything that can help bring drug free and side-effect free relief from chemo-induced nausea, so these "blisslets" are already ahead of the game. Then, add in the cuteness and style - the Cecilia bracelet's unique beaded design and the Aria cuff's sophisticated versatility - and we are ALL in.
