 "Ben Cao Jing Shu" says: "Among the five flavors, only pungent taste can connect the four qi, and it also combines the four flavors. The "Classic" says that the kidney is bitter and dry, and it is urgent to eat pungent food to moisten it. Cuscuta chinensis is one of them. It is completely different from the pungent taste of pungent, fragrant, dry and hot. Scholars should not use the wording to harm the meaning. It is an important medicine for nourishing the spleen, kidney and liver . It is mainly used to heal the broken and injured, replenish the deficiencies, increase the strength and fatten the body. If the three meridians are all full, the broken and injured will be healed and the deficiencies will be replenished. The spleen governs blood, combines muscles and governs the limbs. If the qi of the foot yangming and taiyin is strong, the strength will be long and fat. It nourishes the spleen and nourishes the muscles, it benefits the liver and kidneys and strengthens the yin, strengthens the tendons and bones, warms and replenishes the yang in the kidneys, so it can help the cold essence in the penis to come out and urinate with excess. Bitterness and dryness in the mouth are caused by internal heat due to spleen and kidney deficiency, which results in insufficient body fluids. If the two organs are replenished, the two diseases will heal themselves. If the cold blood is accumulated, overwork will cause blood stasis, and the lack of yang will cause internal coldness. Blood flows with qi, and weak qi cannot control blood flow, which will accumulate over time. All overwork is controlled by the spleen, kidney and liver. If the liver and spleen are strong, blood stasis will come out by itself. "
 "Compendium of Materia Medica": "Dodder seed is a medicine that nourishes the kidney and liver, warms the spleen and helps the stomach. But it is nourishing but not harsh, warming but not dry, so it enters the kidney meridian, and can nourish the deficiency, benefit the excess, warm the cold, cool the heat, dry the dampness, and moisten the dryness. It is not like Phellodendron chinense and Anemarrhena asphodeloides, which are bitter and cold but not warm, and have the qi of draining the kidney meridian; it is not like Cinnamon bark and Alpinia oxyphylla, which are pungent and hot but not cool, and have the dryness of moving the kidney meridian; it is not like Cistanche deserticola and Suoyang, which are sweet and salty and stagnate the qi, and have the dampness of generating the kidney meridian. As "Shennong's Materia Medica" calls it to heal the wound, benefit the qi and strength, and brighten the eyes, all of which are signs of nourishing the kidney and liver, and warming the spleen and stomach."
 "New Compendium of Materia Medica": "Dodder can be used in large quantities or as a single ingredient. For people with weak hearts, day and night dreams, and frequent ejaculation, use three liang of Dodder , ten bowls of water, boil three bowls of juice, and take it in three doses, one dose each in the morning, afternoon, and evening. And never ejaculate again. This is caused by the simultaneous illness of the heart, liver, and kidney meridians, and the deficiency of both water and fire. Dodder is a holy medicine for nourishing the heart, liver, and kidney . Moreover, it is not mixed with other flavors, so it is particularly effective, so it can directly enter the three meridians to achieve full effects. For others who have restless dreams at night, dim eyes, and weak feet, one or two liang can be used, together with ginseng, cooked rehmannia, white atractylodes, and mountain hyssop, and it can achieve miraculous results."
 "Ben Jing Feng Yuan" says: "Dodder seeds dispel wind and brighten eyesight, and are related to liver and kidney qi. Its nature and flavor are pungent, warm and sticky, which is no different from Eucommia ulmoides in strengthening tendons and warming waist and knees. Its function is to benefit essence and marrow, strengthen tendons and bones, stop nocturnal emission, cure cold sperm in the stem, urinate with residual urine, and relieve soreness and weakness of knees and shins. It can be used with Psoralea corylifolia and Eucommia ulmoides for the elderly with liver and kidney qi deficiency, back pain and cold knees. All fascia belong to the liver. For those with qi deficiency and dull pupils, use Ophiopogon japonicus as an adjuvant, and take it in honey pills. It is effective. Do not use it for those with strong yang but not impotence, dry and hard stools, and red and astringent urine, because its nature is biased towards supporting yang ."
 "Compendium of Materia Medica" states: "Dodder is a top-grade herb for nourishing yin and unblocking meridians. Its slightly pungent taste means that there is yang in yin, and it can be kept and moved, which is completely different from other yin-nourishing herbs that tend to be greasy and stagnant. Miao Zhongchun said that among the five flavors, pungent can unblock the four qi. The "Classic" says that pungent can moisten it, and this is the case with Dodder seeds. It is very different from the pungent, fragrant, dry and hot pungent, and the explanation is very sharp. The "Classic" says that it can heal injuries, replenish deficiencies, increase qi and strength, and make people fat and healthy. Among the nourishing herbs, it has the meaning of unblocking all meridians and warming and harmonizing yang. The juice removes facial wrinkles and also softens It has the function of moisturizing the skin. Long-term use will make the yin fluid sufficient and the eyes bright . The so-called nourishing yin and strengthening muscles, strengthening tendons and bones in "Bielu" also means the balance of yin and yang. If the penis is cold and the semen is slippery, it means that the original yang is not suitable and the yin cannot be restrained. If there is residual urine, it means that the kidney yang is not distributed and the qi cannot be raised. If the mouth is bitter and dry and thirsty, it is obviously the dryness of yin fluid, and the accumulation of cold blood is also the stagnation of yang qi. Only this can nourish yin fluid and spread yang and circulate through all meridians, so it can be cured. Compared with the Rehmannia root, which is specialized in replenishing yin and keeping it without moving, it has its own shortcomings. "
