Essential oils are used holistically for various purposes, integrating physical, emotional, and mental well-being. Here's a summary of their common applications with supporting citations:


1. Stress Reduction and Relaxation:

- Essential oils such as lavender, chamomile, and bergamot reduce stress and promote relaxation. Studies have shown that inhaling lavender oil can lower cortisol levels and improve sleep quality (Moss et al., 2012). Similarly, bergamot oil has been found to reduce anxiety and improve mood (Khalifeh et al., 2015).


2. Mood Enhancement:

- Essential oils like citrus oils (e.g., lemon, orange) and rosemary boost mood and energy levels. Research indicates that citrus oils can enhance mood and cognitive performance (Moss et al., 2008), while rosemary oil has been shown to improve concentration and alleviate feelings of fatigue (Gardner et al., 2003).


3. Pain Relief:

- Certain essential oils, including peppermint, eucalyptus, and ginger, are used for their analgesic properties. Peppermint oil, for example, contains menthol, which can relieve headaches and muscle pain (Cavanaugh et al., 2009). Eucalyptus oil is also used for its anti-inflammatory and pain-relieving effects (Huang et al., 2010).


4. Immune Support:

- Essential oils such as tea tree, oregano, and eucalyptus are used to support immune health. Tea tree oil has well-documented antimicrobial properties (Carson et al., 2006), while oregano oil is known for its potential antiviral and antibacterial effects (Guilford et al., 2017).


5. Skin Care:

- Essential oils like lavender, tea tree, and rose have applications in skin care for their antiseptic, anti-inflammatory, and regenerative properties. Lavender oil, for instance, can promote wound healing and reduce scarring (Shin et al., 2011), while tea tree oil is effective against acne (Enshaieh et al., 2007).


6. Digestive Health:

- Oils such as ginger and peppermint are used to aid digestion and alleviate gastrointestinal discomfort. Ginger oil can reduce nausea and improve digestive function (Takahashi et al., 2012), and peppermint oil is known to relieve symptoms of irritable bowel syndrome (IBS) (Moss et al., 2010).
