It's true. The characteristics of agarwood pillow are good for insomnia, cervical vertebra, lumbar vertebra, migraine and other diseases. Please bring your own pillowcase when using. It feels soft and hard. The smell of agarwood is naturally not pungent, and there is a feeling of alcohol. However, because artificial spices or other chemicals are added to the fake agarwood, the aroma will have a pungent feeling when it enters the nose, which is a very unnatural fragrance. When you sleep at night, put agarwood on your pillow. If the fragrance comes in waves, it is fake. If it is really heavy, it is an endless fragrance. Don't smell agarwood too close, put it at a distance from your nose. If you can smell it, put it away. Good agarwood has a large smell coverage.
