Antioxidant Activity of Linalool in Patients with Carpal Tunnel Syndrome
Antioxidant Activity of Linalool found in Essential Oils in Patients with Carpal Tunnel Syndrome
A study was done at the Center for Plastic and Reconstructive Surgery in Seoul, Korea in 2016. It was published in BMC Neurology. Researchers explored the effects of linalool, a component in essential oils, on oxidative stress in patients suffering from carpal tunnel syndrome (CTS). CTS is a common condition caused by pressure on the median nerve in the wrist, leading to pain, numbness, and functional difficulties.
Essential Oils with High Levels of Linalool:
Lavender Oil: One of the richest sources of linalool, containing up to 50-60% of this compound, making it popular for relaxation and stress relief.
Bergamot Oil: Contains approximately 30-35% linalool, contributing to its uplifting aroma and calming effects.
Coriander Oil: Contains around 60-70% linalool, which is responsible for its sweet and spicy scent, often used in both culinary and therapeutic applications.
Rosewood Oil: Typically has about 70-90% linalool, valued for its floral fragrance and use in skin care.
Sweet Basil Oil: Contains around 25-50% linalool, known for its refreshing scent and potential anti-inflammatory properties.
Thyme Oil (Thymus vulgaris): Particularly the thymol-free variety, contains significant amounts of linalool (up to 50%).
Note: These essential oils not only provide therapeutic benefits but are also commonly utilized in aromatherapy for their calming and soothing properties, making them excellent choices for conditions like anxiety and stress, as well as potentially benefiting carpal tunnel syndrome.
Key Findings of the Study:
Linalool's Antioxidant Effects: The study demonstrated that inhalation of linalool significantly increased antioxidant activity in patients with Carpal Tunnel Syndrome. This suggests that linalool could help combat oxidative stress, which is considered a contributing factor in the condition.
Blood Pressure and Heart Rate: Participants inhaling linalool experienced a reduction in blood pressure and pulse rate, indicating a potential calming effect on the body.
Study Design: A total of 37 participants (both with and without CTS) were randomly assigned to inhale either 1% linalool or a placebo (carrier oil). Various health metrics were measured before and after the inhalation sessions.
Implications for Essential Oils in CTS Treatment:
The findings imply that essential oils for carpal tunnel syndrome, particularly those containing linalool, may provide a non-invasive option to reduce symptoms associated with oxidative stress and improve overall well-being in patients. Given the limitations of current treatments, including surgery and steroid injections, the use of linalool presents a promising alternative for managing CTS symptoms and enhancing quality of life.
This study highlights the potential role of essential oils as a complementary therapy for those suffering from carpal tunnel syndrome, paving the way for further research in this area.
Conclusion:
In summary, the study on linalool’s effects in patients with carpal tunnel syndrome shows that essential oils can be a helpful addition to treatment. Linalool, particularly found in oils like lavender, bergamot, coriander, rosewood, sweet basil oil and thyme oil not only boosts antioxidant levels but also helps lower blood pressure and heart rate. This suggests that using linalool-rich essential oils could provide a natural way to ease symptoms and improve well-being for those with carpal tunnel syndrome. Further research is needed to explore the best ways to incorporate these oils into healthcare practices.
