The illustrations, also known as the food poisoning diagrams, teach the public in a graphic way what food combination causes poisoning and how to detoxify. They are commonly found on the back cover of farmers’ almanac in Taiwan. It is said that they appeared as early as the Japanese rule period in Taiwan, and many of them have proved with evidence to be almost entirely superstitions or misinformation of erroneous causal relationships or caused by improper preservation and cooking methods.
The farmers’ almanac is the reference book of lunar terms and daily life of the agricultural society. It is the experiences and observations of Chinese culture handed down through history. After thousands of years of compilation and enrichment of various contents, it is now completed and circulated. It also includes the food poisoning illustration attached to the back cover.
