Many herbal distillates are used the way that essential oils are. If you are using a specific oil for your depression or anxiety, you may add some drops to a humidifier or diffuser for relief. With the herbal distillates you would do the same thing except the consistency of the product is water as opposed to oil. This can sometimes work really well because oil and water don't mix. However, hydrosol water will easily mix with the water that is needed to run the device. It will potentially last longer as well because the water is able to be evenly distributed unlike oil which stays relatively solid as it moves around the water.
