Chamomile is also used in external applications, such as in salves and lotions that treat mild skin problems such as rashes and burns. It is also used in salves to relax tired and sore muscles. You'll also find chamomile in shampoo, some cosmetics, and in bath salts. Chamomile is pretty much allergy-free, and is a good alternative to products that contain chemicals and unnatural ingredients in these instances.
Lately it's been used a lot in aromatherapy applications, and chamomile oil is being used as a type of deodorizer and air freshner. A few people I know use it for that purpose and have nice smelling homes - a better alternative than Fabreze and other similar commercial products.
There are several varieties of chamomile, all with different aromatic profiles depending on the species and where it's grown. Smell the different types of chamomile oil to find just what you are looking for.
Chamomile plants have been used in gardens as a natural insecticide, and some people think of the plant as bringing good luck.
I've been enjoying chamomile in tea since the ol' hippy days back in 1967-68. And every now and then I'll put some dried chamomile in a vase and stick it somewhere in the house, but my cat sometimes attacks it, so I don't do that too often these days.
