Does the illustrated materia medica refer to peanuts or rape?

Rape flower, as recorded in Su Song's "Herbal Painting" in the Northern Song Dynasty: "Oil leaves are better than others, and the dishes are fragrant, which makes the candles bright, the points bright, and the paintings black and moist. Feeding pigs with cakes is easy to fatten, and the fields are flourishing."

Before the Song Dynasty, rapeseed was mainly eaten as a vegetable. In the Song Dynasty, it was found that rapeseed could be used to extract edible oil. Su Song recorded that rapeseed was used to extract oil, which could be added to vegetables to make lanterns and candles. The residue after oil pressing can be fed to pigs and used as fertilizer.

Introduction to illustrated materia medica

There are 780 kinds of medicinal strips in the book "Illustration of Materia Medica" (2 1 volume), including new drugs (kloc-0/03) and 933 sketches of 635 kinds of medicines, most of which are realistic and lifelike. In fact, this book is a comprehensive description of the species and forms of plants, with pictures and texts.

The compilation of Illustrated Materia Medica is that the government ordered all counties in the country to draw all the medicines produced, regardless of animals, plants and minerals, and indicate the flowering and fruiting season and function of plants (for imported foreign medicines, the customs authorities and businessmen should be asked to identify the source), and one or two samples should be sent to Kyoto for painting.
