Claim Text:
1. An apparatus for extracting an essential oil from an essential oil-containing material, the apparatus comprising: a container configured to hold an essential oil-containing material and configured to transmit microwaves through the container to the essential oil-containing material to cause the essential oil to vaporize; a condenser coupled to the container and configured to receive and condense essential oil-containing vapor emitted by essential oil-containing material within the container, wherein the condenser comprises a volume of condensing material having a temperature below a condensation temperature of the received vapor such that the received vapor condenses on the condensing material; a microwave blocking shield positioned around the condensing material, the shield comprising a plurality of holes that allow received vapor to pass through the shield to reach the condensing material but do not allow microwaves to pass through the shield to reach the condensing material; and an essential oil extract receiver positioned within the container and below the condenser and configured to receive condensed essential oil from the condenser; wherein the apparatus has an overall dimension that is sized to fit inside a microwave oven.
