The present invention is to provide a mixing circuit, comprising: a first transistor; a second transistor; a third transistor; a first connection point connected to a gate terminal of the first transistor, a drain terminal of the second transistor and a source terminal of the third transistor; a second connection point connected to a source terminal of the first transistor and a gate terminal of the second transistor; and a third connection point connected to a drain terminal of the first transistor and a drain terminal of the third transistor.

Mixing circuit

The invention discloses an extract containing puccoon and Chinese angelica, and a formula and preparation method of an ointment containing the extract. The extract is used for treating burns and scalds and is characterized by superior shelf-life. The puccoon and Chinese angelica are extracted with an organic solvent having a polarity of between 0.35 and 0.95, which are then filtrated, concentrated and mixed with a physiologically acceptable carrier or excipient.
