Most Cedarwood oil can be put on the skin. test a little drop on your skin and see what happens.
As an oil, you can sniff it from the bottle which is what I like to do. You can see if you can wear it on your skin and you can put it in an oil diffuser (electric or candle) and let the oil be vaporized.
As for chips: dropping a few Cedar chips on some hot charcoal does wonders.
As for sleeping: some people use Cedarwood. Some people, especially some with allergies, use Sandalwood.
Happiness is the result of an enlightened mind whereas suffering is caused by a distorted mind.
