Asian cultures have been sleeping on buckwheat pillows for hundreds of years, but it wasn't until the 1980s that western cultures began to appreciate the benefits of buckwheat pillows.

Buckwheat is commonly mistaken for a grain, while it is actually a fruit. Buckwheat (fagopyrum esculentum), is related to the rhubarb family. Buckwheat pillows are stuffed with hulls of buckwheat, the husks that protect the kernels. Buckwheat hulls are roasted to remove dust from the growing fields, before before being placed into the pillowslips.

Buckwheat is a natural, inexpensive and renewable resource, unlike the petroleum-based foam used in many pillows. In addition to environmental bonuses, buckwheat pillows provide excellent support for the head, neck and back because the hulls contour to the weight and shape of the body during sleep. Buckwheat pillows also provide natural air circulation between individual hulls, resulting in ideal temperatures for peaceful sleeping.

Buckwheat pillows have become a staple cushion for yoga students, but they are found mainstream as well. Some of the swankiest hotels worldwide have begun offering buckwheat pillows to their guests as an alternative because of their increased popularity.

Manufacturers of buckwheat pillows have expanded their lines. Aside from the standard bed pillow, buckwheat pillows are available in full-body sizes similar to a futon. They are also offered as keyboard wrist rests, eye pillows, travel pillows, and neck-rolls. There are even tubular buckwheat pillows with straps, used for lumbar support while driving, working, or sitting at a desk. Some manufacturers have taken to adding herbs, such as lavender and chamomile, to the buckwheat hulls to add a touch of aromatherapy.

Many healthcare professionals have started recommending a buckwheat pillow to patients suffering from such conditions as migraines, snoring, insomnia and menopausal night sweats.

Some people are allergic to buckwheat pillows, but this is usually a result of dust-covered hulls. To eliminate that possibility, buy only top quality buckwheat pillows produced by manufacturers that roast the hulls. Many cheaper buckwheat pillows are filled with hulls that have been vacuumed, not roasted, which could leave dust residue that might trigger an allergy.

A good quality buckwheat pillow can last for 7-10 years with proper care. The outside cotton cover should be washed regularly, but do not wash the pillow itself. Instead, the buckwheat pillow should be set in direct sunlight for a few hours once every two months or so.
