The Global Wellness Institute states that there were over 149,000 spas across the world in 2017 and there are 740 wellness lifestyle real estate communities partially built, under development, or completely built across 34 countries. In recent years, spas and wellness centers have become extremely popular, because they offer treatments for stress, anxiety, and skin problems. To offer remedies for such problems, spas and wellness centers are increasingly using essential oils in their treatment procedures. Thus, the soaring number of spas will create a huge requirement for essential oils in the foreseeable future.

Additionally, the burgeoning demand for aromatherapy will also contribute to the essential oils market growth during 2021–2030. According to P&S Intelligence, the market generated $11 billion revenue in 2020. Aromatherapy is defined as an alternative treatment procedure that utilizes naturally harvested aromatic essences to balance, harmonize, and support the mental and physical health of patients suffering from respiratory infections, skin disorders, anxiety or stress, and fatigue. As a large number of people are currently living a hectic life, they are always seeking an alternative way to relieve stress and relax their bodies.
