Daji Gen (Radix Cirsii Japonici), its content is documented under the entry for Xiaoji Gen (Radix Cirsii Japonici).

Ai Ye (Folium Artemisiae Argyi), ancient texts do not specify its place of origin, only stating that it grows in fields. It is now found everywhere, and those described as "fudao" (growing densely/luxuriantly) are considered superior. It is said that moxibustion with this type of Ai Ye is particularly effective for treating various diseases. In early spring, shoots emerge close to the ground; the stems resemble mugwort (Artemisia species), but the leaf backs are white, and those with shorter shoots are preferred. Leaves should be harvested on the third day of the third lunar month and the fifth day of the fifth lunar month, sun-dried, and used only after aging for a long period. Folk practice also involves crushing fresh leaves to extract juice for drinking, which can stop evil qi in the heart and abdomen. Ancient prescriptions also use cooked Ai Ye to apply to golden wounds (traumas caused by metal weapons). For treating wind-stroke characterized by pulling pain, numbness, and immobility, take a large amount (approximately one hu) of dry Ai Ye, roll it into a ball, place it in a clay steamer (zeng), seal all holes except one, position the painful area under the opening, burn the Ai Ye for one shichen (two hours), and continue this practice over time. To treat leprosy-like diseases, take an appropriate amount of dry Ai Ye, soak it in yeast to brew wine according to standard methods, and drink it; if a sensation of bi-syndrome relief is felt, the condition improves. In recent times, some people consume Ai Ye alone, either steamed with papaya pills or decocted and drunk on an empty stomach. It greatly tonifies deficiency and emaciation, yet it possesses toxicity. When toxicity manifests, hot qi rushes upward, causing uncontrollable mania and restlessness, potentially attacking the eyes to cause sores and bleeding. Therefore, it must not be taken recklessly.

Shui Ping (Herba Lemnae), originally growing in the ponds and marshes of Lei Ze, is now found in streams and ditches everywhere. This is a large variety of aquatic duckweed, with round leaves about one cun wide, and a foam-like spot underneath each leaf. It is also known as Xing Cai (Nymphaea tetragona), referred to as Fen in the *Erya*. The larger ones are called Ping. The *Book of Songs* (Zhou Nan) states: "Where to gather Ping?" Lu Ji stated: "The coarse floating plants in water are called Ping." They begin to grow in late spring and can be mixed with flour and steamed as a vegetable. They can also be pickled in vinegar as an accompaniment to wine. Harvested in March and sun-dried. Su Gong stated there are three types: the largest is Ping; the medium-sized is Xing Cai (also known as Fu Kui); the smallest is Shui Shang Fu Ping (floating duckweed), which grows in ditches. Large Ping is rarely used in modern medical prescriptions. Floating duckweed (Fu Ping) is commonly used by folk physicians to treat epidemic febrile diseases and is effective in inducing sweating. One prescription uses one liang of Fu Ping herb (harvested on the fifteenth day of the fourth lunar month), half a liang of Mahuang (Ephedrae Herba) with nodes and roots removed, half a liang of Guixin (Cinnamomi Ramulus), and half a liang of Fuzi (Aconiti Lateralis Radix Praeparata) processed by cracking and removing the umbilical skin. These four ingredients are finely pounded and sifted. Take two qian per dose, add one zhong of water and half a fen of fresh ginger, decoct until six parts remain, and drink hot with the dregs at any time. Recovery occurs when sweat appears. Another method treats severe diseases with widespread sores by taking concentrated decoction of aquatic floating duckweed and bathing in it for half a day, which is often effective. This prescription is quite unique and ancient.
