bubble_chart Formula Principles

Tongrentang Prescription Explanation: Maiwei Rehmannia Pill, based on the Six-Ingredient Rehmannia Pill, nourishes kidney yin, restoring deficient kidney yin; combined with Ophiopogon Tuber to clear and nourish lung yin, relieving heat and irritability, nourishing and strengthening; lubricating and reducing inflammation; paired with Schisandra Fruit to nourish the kidney and astringe lung qi. The combination of eight medicinal ingredients works together to nourish the kidney and lung, primarily used to treat symptoms caused by lung-kidney yin deficiency such as tidal fever, night sweats, dry cough with blood, vertigo, tinnitus, etc. It is particularly effective for symptoms like dry throat, thirst, cough, and blood in sputum caused by prolonged coughing damaging yin or consumptive diseases (such as pulmonary subcutaneous nodules). (Applicable to various symptoms of lung-kidney yin deficiency.)
1. Original Entry Explanation: Ophiopogon Tuber can clear and nourish lung yin, with effects such as relieving heat and irritability, nourishing and strengthening, lubricating and reducing inflammation, treating cough with dyspnea, antiemetic, thirst-quenching, hemostatic, promoting lactation, diuretic, and treating chronic wind-dampness arthralgia; Schisandra Fruit not only nourishes the kidney and astringes the lung, but modern use for dizziness, blurred vision, headache, insomnia, and other general neurological disorders has also achieved good results. This medicine enhances the function of enriching yin and producing fluid compared to the Six-Ingredient Rehmannia Pill, making it an effective remedy for lung-kidney yin deficiency and cough with deficiency-type dyspnea. (Applicable to cough and asthma due to lung-kidney yin deficiency.)
2. Nie Wentao's Explanation: Diabetes was first mentioned in Huangdi Neijing•Qibing Lun, named consumptive thirst. In Chinese medicine, consumptive thirst is discussed as lung heat damaging fluid, excessive thirst and drinking as upper consumptive thirst; stomach fire blazing, rapid digestion and frequent hunger as middle consumptive thirst; kidney failing to control water, frequent urination as lower consumptive thirst. Lung dryness, stomach heat, and kidney deficiency coexist, with possible emphasis on one, forming consumptive thirst, and the absence of any one prevents the disease. Rehmannia Pill, now known as Six-Ingredient Rehmannia Pill, with three tonics and three purgatives, excels in tonifying kidney yin and purging dampness turbidity and deficient fire. The Pharmacopoeia of the People's Republic of China states that the Six-Ingredient Rehmannia Pill is suitable for consumptive thirst, and Maiwei Rehmannia Pill is based on Rehmannia Pill with the addition of Ophiopogon Tuber and Schisandra Fruit, enhancing the function of astringing the lung and absorbing the kidney. Therefore, the Pharmacopoeia of the People's Republic of China records Maiwei Rehmannia Pill as nourishing the kidney and lung, used for lung and kidney yin deficiency, tidal fever, night sweats, dry cough with blood, vertigo, tinnitus, soreness and weakness of the waist and knees, and consumptive thirst. (Applicable to consumptive thirst due to lung-kidney yin deficiency.)

   bubble_chart Comparison

   The OTC regulations take into account that Maiwei Rehmannia Pills contain sugar (honey), thus warning diabetic patients to be cautious; they also consider that Maiwei Rehmannia Pills contain Ophiopogon Tuber, thus advising hypertensive patients to be cautious, and so on. The Pharmacopoeia, on the other hand, places more emphasis on the long-term practice of Chinese medicine and pharmacological research. In fact, the presence of honey in Maiwei Rehmannia Pills is more beneficial in alleviating the internal drive for elevated blood sugar levels, hence the Pharmacopoeia supports its use for consumptive thirst syndrome.

   Comparison: OTC focuses on drug safety considerations, meaning that drugs should avoid potential unsafe factors. The Pharmacopoeia emphasizes drug efficacy considerations, meaning that the primary purpose of drugs is to treat diseases, and then other aspects. Together, they form the contemporary health protection system for the nation.
