Traditional Chinese herbal aroma sachet, made from fragrant and aromatic herbs, is a form of  ‘Yi Guan Liao Fa’ (translated as ‘clothing therapy’). The ancient Chinese believe that when these aromatic herbs are worn on the body or hung indoors, the unique aroma acts on the brain and helps with the prevention and treatment of minor ailments. Furthermore, aroma sachets originate from Chinese culture, where historically, the gifting and wearing of these aroma sachets are a symbol of care and blessing between family members. Studies have found that the aromatic compounds can increase immunity, calm nerves and promote sleep.
