Aromatherapy is a comprehensive therapeutic practice that has been utilized since ancient times to address mental and physical disorders. Plant-derived essential oils are inhaled or absorbed via the skin to boost mental well-being and alleviate physical suffering. This practice is not always accepted as a viable type of treatment in the medical world today, although this is primarily due to a lack of study. Essential oil research is restricted and troublesome, in part because study participants can distinguish different oils by smell, and hence the conclusions cannot be randomized or unbiased.
