[Winter Okra] It is the primary vegetable among the five vegetables. Those sown in autumn and maturing early are called "Dongkui" (Winter Okra) when they produce seeds in spring. Its core contains poison that harms the human body; its nature is cold. Consuming it hot can cause a conflict between cold and heat, chest tightness, and shortness of breath, and may even stir up wind pathogens. Eating frozen Dongkui raw can induce five types of tumor-like fluid retention diseases, and in severe cases, vomiting of clear water. Consuming it with carp is harmful to humans. One should not eat raw Dongkui in any season, as it is difficult to digest and can trigger all kinds of chronic diseases. It should be avoided while taking various medicines, otherwise it may cause madness. Wu Kui (also known as Shu Kui) bitten by dogs is inedible; it dulls one's mental faculties. If consumed after being bitten by a dog, the condition will never heal. Consuming Xu Kui along with bird meat results in a lackluster complexion.

The flower stirs up wind; it should not be eaten after the Qingming Festival as it is detrimental to patients, exacerbating conditions of chronic cold in the heart and abdomen. Frost-exposed chives are inedible as they stir up retained fluids leading to vomiting of water.
