Vapes designed to heat herbs in their natural form are widely known as dry herb vaporizers or herbalizers.
Certain aromatics, flowers, and herbs can be dried, crushed, and then inserted into your dry herb vape. This dried plant material can be used for meditative practice, medicinal application, and recreational use.
While smoking, the vape oven chamber is what heats up your dry herbs. This is then released as a vapor and inhaled.
