Promotes Relaxation
Inducing relaxation is a traditional use of lavender tea, primarily because of the soothing aroma. Studies suggest that inhaling the scent of lavender may slow nervous system activity, promoting relaxation. This can help with anxiety, insomnia, stress and depression. One small study published in the September 2011 edition of the "Journal of Alternative and Complementary Medicine" found that patients who were treated by inhaling lavender oil experienced significant reduction in stress levels and reduced levels of pain when hypodermic needles were inserted. Preparing lavender tea helps release the oils responsible for the beneficial aroma.
Digestive Issues
Another common traditional use for lavender tea is for digestive issue relief, including nervous stomach and indigestion. Modern studies suggest that this may be a valid use. One study found that the smooth muscle -- in the intestines responsible for moving food through the digestive system -- of rats would relax when lavender oil was applied, indicating that humans may be affected the same way. Another study reported that lavender oils protected against Peptic Ulcer, Chronic Gastritis.
Convulsions and Spasms
A convulsion occurs when a muscle contracts and relaxes rapidly involuntarily, causing the body to shake. A spasm is similar, but it usually results in a muscle staying contracted. Lavender oil has been found to be a benefit in reducing both spasms and convulsions. A study found that rats given a small dose of lavender experienced reduced convulsions and spasms, which was thought to be a result of the lavender blocking the calcium channel -- a key part of the muscle contraction process.
