Chamomile has been used medicinally for thousands of years and is widely used in Europe. It is a popular treatment for numerous ailments, including sleep disorders, anxiety, digestion/intestinal conditions, skin infections/inflammation (including eczema), wound healing, infantile colic, teething pains, and diaper rash. In the United States, chamomile is best known as an ingredient in herbal tea preparations advertised for mild sedating effects. German chamomile ( Matricaria recutita ) and Roman chamomile ( Chamaemelum nobile ) are the two major types of chamomile used for health conditions. They are believed to have similar effects on the body, although German chamomile may be slightly stronger. Most research has used German chamomile, which is more commonly used everywhere except for England, where Roman chamomile is more common. Although chamomile is widely used, there is not enough reliable research in humans to support its use for any condition. Despite its reputation as a gentle medicinal plant, there are many reports of allergic reactions in people after eating or coming into contact with chamomile preparations, including life-threatening anaphylaxis.
Perilla is a traditional crop of China, India, Japan, Korea, Thailand, and other Asian countries. In North America, it is occasionally called by its Japanese name, shiso . In North America, it is also known as purple mint, Chinese basil, or wild coleus. Perilla seed oil is used for cooking, as a drying oil, and as a fuel. Perilla seed oil is high in the omega-3 fatty acid, alpha-linolenic acid. Asian practitioners prescribe perilla for respiratory afflictions and prevention, pregnancy concerns, seafood poisoning, and 'incorrect energy balance.' Some evidence is available for the use of perilla oil for reduction in asthma symptoms, as well as use of perilla extract for seasonal allergies. More clinical evidence is required before recommendations can be made for any clinical usage of perilla.
