Osmist Dry Mouth Spray

Osmist was developed as a solution to dry mouth or xerostomia but began as a passion project of one dedicated Australian. Backed by clinical research, she refined a formula over multiple trials to ensure the most effective ingredients were used and to improve the user’s quality of life. 

And the person responsible for spearheading this endeavour was speech pathologist, Martha Rowe.

Meet Martha Rowe

At 3 years of age, Martha was in a childhood accident which left her with unhealed, hairline fractures throughout her face. In her early adult years, metal plates needed to be placed across these hairline fractures. This meant that the surgeons would have to operate by going in through Martha’s mouth. As a result of the surgery, Martha then suffered for many years with “dry mouth” syndrome also known as “xerostomia”.

Martha became a speech pathologist where she developed in-field expertise and gained an understanding of how dry mouth was affecting her patients. Due to her own surgery, Martha had firsthand experience with finding dry mouth solutions. Disappointed by the unsatisfactory relief with commercially available products, Martha started to work on developing her own formula. Using her experience as a speech pathologist she started a trial and error process of trying to find the most effective solution. Thus began the creation of Osmist.

Clinical Research

Developed over many years and multiple trials, the Osmist formula was refined through research by Martha Rowe and a team of science professionals.


Studies first began in 2008, with a trial of 100 participants suffering from dry mouth. This served as a basis for Martha’s further research as it examined the microbiological and immunological outcomes of specific ingredients and investigated the quality of life impact of the dry mouth solution.


Martha continued her studies again with another performed in 2013, assisting patients with chronic dry mouth. This study aimed to refine the impact of the formula in increasing saliva flow rate, to ensure the product didn’t just hydrate the mouth but would be able to encourage saliva production and allow for longer lasting relief. Further research and trials continued, culminating in a study in 2018.
