Abstract
Description
A medicinal and edible tea for relieving summer heat and dampness, its preparation method and application Technical Field This invention belongs to the field of health food technology, specifically relating to a medicinal and edible tea that relieves summer heat and dampness, its preparation method, and its application. Background Technology Heat damage can cause a series of pathophysiological changes in the body, manifesting as a continuous process from mild to severe, including heat exhaustion, mild heatstroke, and severe heatstroke. Heatstroke is the most serious type of heat-related illness with a high mortality rate. In relevant literature describing heat-related illnesses, concepts such as "heat cramps," "heat syncope," and "heat exhaustion" are frequently used. Heatstroke is a life-threatening clinical syndrome caused by an imbalance between heat production and dissipation due to exposure to hot environments and / or strenuous exercise. It is characterized by a core temperature exceeding 40°C and central nervous system abnormalities, such as altered mental status, seizures, or coma, often accompanied by multi-organ damage. Based on the cause and susceptible population, heatstroke is classified into classic heat stroke (CHS) and exertional heat stroke (EHS). CHS is primarily caused by high temperature and / or high humidity, usually without strenuous physical activity. Individuals with impaired thermoregulation are more susceptible, such as infants, the elderly, patients with chronic underlying diseases, those who are bedridden for extended periods, and obese individuals. The susceptibility factors for EHS vary considerably. In recent years, my country's climate has been characterized by smaller regional temperature differences, longer periods of high temperatures, and summer high temperatures exceeding 39°C in some areas. Statistics show that the number of heatstroke cases and related deaths in my country is increasing year by year. Prodromal symptoms of heatstroke (CHS) are often difficult to detect, with symptoms worsening over 1-2 days, including confusion, delirium, and coma, with body temperature rising to 40-42°C. It is often accompanied by urinary and fecal incontinence, heart failure, and kidney failure. Excessive heatstroke (EHS) occurs after a period of high-intensity training or heavy physical labor in hot and humid environments, but some patients may also develop the disease without warning signs, suddenly collapsing or losing consciousness during exercise. Clinical manifestations can vary considerably among patients, and may even be atypical. Traditional Chinese medicine classifies heatstroke into "yang heatstroke" and "yin heatstroke." In summer, due to the hot weather, people seek coolness by blowing in the wind or drinking excessive amounts of cold beverages, leading to a deficiency of vital energy (qi). This deficiency allows the pathogenic factors of summer heat and wind-cold (dampness) to invade and cause illness. Because it is contracted through stillness, it is called "yin heatstroke." Zhang Jiebin of the Ming Dynasty, in his *Jingyue Quanshu*, pointed out that "Yin summer heat is caused by catching a cold due to summer heat. People who fear the heat and crave coolness, failing to avoid the cold, may be in deep halls or large buildings, in windy places or under trees, or during periods of sudden heat or cold, without proper clothing and bedding. This allows cold pathogens to invade the skin, causing symptoms such as fever, headache, lack of sweating, chills, stiffness, and aches in the limbs. This is called Yin summer heat due to catching a cold in the summer months, and it is essentially a form of typhoid fever. The treatment should focus on warming and dispersing, and should be treated according to the methods for typhoid fever. Furthermore, carelessness in eating raw or cold foods can lead to internal damage from cold, causing symptoms such as vomiting, diarrhea, and abdominal pain. This is also caused by catching a cold due to summer heat, but since the cold pathogen is internal, the treatment should focus on warming the middle jiao; this is also a form of Yin summer heat." He further stated, "Therefore, among those suffering from summer heat, Yang summer heat is rare, while Yin summer heat accounts for eight or nine out of ten cases." Yin summer heat is common in summer, often presenting with symptoms such as dizziness, heaviness in the body, joint pain, fatigue, chest tightness, nausea, dry mouth, bitter taste, abdominal pain, and diarrhea. The progression from heat exhaustion and mild heatstroke to heatstroke is a gradual and continuous process. Intervention should be initiated as soon as abnormalities are detected, not after a diagnosis of heatstroke is established. Once heatstroke develops, it progresses rapidly and often involves multiple organ dysfunction, while clinical treatment options are limited. Unlike other critical illnesses, heatstroke is entirely preventable. It should be emphasized that the key to reducing the mortality rate of heatstroke lies in prevention rather than treatment. Currently, Western medicine's treatment principles are to monitor body temperature, maintain fluid balance, and manage complications. Treatment methods for "yin-type heatstroke" are even more limited. Therefore, in the stages of heat exhaustion and mild heatstroke, when the TCM syndrome is classified as "yin-type heatstroke," intervention with traditional Chinese medicine can be very helpful. Summary of the Invention The purpose of this invention is to provide a medicinal and edible tea substitute for relieving summer heat and dampness, as well as its preparation method and application, in order to solve the aforementioned problems. According to one aspect of the present invention, the present invention provides a medicinal and edible tea substitute for relieving summer heat and dampness, which is prepared from the following raw materials in parts by weight: 3-20 parts of patchouli, 2-20 parts of sesame, 5-30 parts of codonopsis, and 1-15 parts of dried tangerine peel. In this formula, Agastache rugosa is the chief ingredient, pungent and slightly warm in nature, used to relieve summer heat, resolve dampness, and stop vomiting; Elsholtzia ciliata is the assistant ingredient, slightly warm in nature, used to induce sweating, relieve exterior symptoms, resolve dampness, and harmonize the middle jiao. The two ingredients work together to relieve summer heat and dispel dampness. The *Feng's Secret Records* states, "In the long, hot summer, dampness prevails, so summer heat is always accompanied by dampness, hence spontaneous sweating." Codonopsis pilosula is the adjuvant ingredient, sweet and neutral in nature, entering the spleen and lung meridians. *New Compilation of Materia Medica* states, "It tonifies the middle jiao and benefits qi, harmonizes the spleen and stomach, and relieves thirst. It is very safe to use to regulate and tonify when the middle jiao is slightly deficient." *Correct Interpretation of Materia Medica* also states, "It strengthens the middle jiao and is not much different from ginseng." Tangerine peel is the guiding ingredient, pungent and fragrant, good at regulating qi and harmonizing the middle jiao to ensure its orderly rise and fall, most suitable for qi stagnation due to cold and dampness obstructing the middle jiao. *Compendium of Materia Medica* states, "It treats all diseases by regulating qi and drying dampness. It tonifies when used with other herbs and drains when used with other herbs." Therefore, the combination of these two components can replenish qi without causing qi stagnation, and promote qi circulation without excessively depleting qi, thus harmonizing the spleen and stomach. It is especially suitable for people suffering from summer heat and dampness due to wind-cold. This formula combines the functions of gently dispersing, resolving dampness, replenishing the middle jiao, and regulating qi, and has the effects of relieving summer heat and releasing the exterior, aromatically resolving dampness, and regulating qi and strengthening the middle jiao. Summer temperatures are higher and the heat is more intense. With improved living conditions, people tend to indulge in cold drinks and beverages, allowing cold and dampness to invade the body during the summer, causing various discomforts and forming "yin heatstroke." Yin heatstroke is particularly common in summer, caused by the invasion of summer heat and wind-cold-dampness pathogens when the body is weak. Symptoms often include dizziness, heaviness in the body, joint pain, fatigue, chest tightness, nausea, dry mouth, bitter taste, abdominal pain, diarrhea, pale tongue, thick and greasy tongue coating, and a floating and slippery pulse. This invention uses the methods of traditional Chinese medicine to treat heatstroke by relieving summer heat, dispelling dampness, and regulating qi and strengthening the middle jiao, which can effectively improve the clinical symptoms of heatstroke in patients. The raw materials for this formula come from the following sources: Patchouli: The aerial parts of Pogostemincablin (Blanco) Benth. or Agatacherugosus (Fisch. et Mey) O. Ktze., plants belonging to the genus Pogostemincablin in the Lamiaceae family. Elsholtzia: The aerial parts of *Mosla chinensis* Maxim. or *Mosla chinensis* Jiangxiangru, both belonging to the genus *Mosla* in the family Lamiaceae. Codonopsis pilosula: The root of Codonopsis pilosula (Franch.) Nannf., Codonopsis pilosula Nannf. var. (Nannf.) L.Shen, or Codonopsis tangshen Oliv., all belonging to the genus Codonopsis of the family Campanulaceae. Dried tangerine peel: The dried, mature peel of Citrus reticulata Blanco and its cultivated varieties, belonging to the Rutaceae family and the Citrus genus. The raw materials in the herbal composition of this invention, namely, agastache rugosa, euphorbia humifusa, codonopsis pilosula, and tangerine peel, belong to substances that are "both food and traditional Chinese medicine" (as stated in the "Notice of the Ministry of Health on Further Regulating the Management of Raw Materials for Health Foods").
[2002] According to Announcement No. 51 and Announcement No. 9 of 2023, regarding 9 newly added substances that are traditionally both food and Chinese medicinal materials, the raw materials in the formula are all Chinese medicinal materials that can be used in health food, and their sources are safe and reliable. In some embodiments, the preferred proportions of the above-mentioned raw materials are: 5-15 parts of patchouli, 3-15 parts of euphorbia humifusa, 8-18 parts of codonopsis pilosula, and 1-10 parts of dried tangerine peel. In some embodiments, the proportions of the above-mentioned raw materials can be further preferred as follows: 10 parts of patchouli, 5 parts of euphorbia humifusa, 10 parts of codonopsis pilosula, and 3 parts of dried tangerine peel. In some embodiments, the aforementioned medicinal and edible herbal tea for relieving summer heat and dampness may also include medically or food-grade excipients to prepare different dosage forms required by patients, facilitating use, storage and transportation, and meeting clinical and market demands; wherein the excipients used are all commonly used excipients in the prior art. In some embodiments, the medicinal and edible tea substitute for relieving summer heat and dampness can be in the form of oral solution, powder (such as making into a solid beverage), granules, etc. Among them, the tea substitute of this application is mostly taken in the form of oral solution, which is convenient for patients to carry and take. According to another aspect of the present invention, the present invention also provides a method for preparing a medicinal and edible herbal tea for relieving summer heat and dampness. When the herbal tea is an oral solution, the preparation method includes the following steps: The raw materials are soaked in water, then heated to boiling and kept at a gentle boil for 0.8-2 hours. After separation, the first decoction and the residue are obtained. Water is added to the residue, heated to boiling and kept at a gentle boil for 0.8-2 hours. After separation, the second decoction is taken. The first and second decoctions are combined to obtain an oral solution. In some embodiments, the raw materials are added to water in 8-40 times their total weight and heated to boiling, while the dregs are added to water in 6-30 times their total weight and heated to boiling. According to another aspect of the present invention, the present invention also provides a method for preparing a medicinal and edible tea substitute for relieving summer heat and dampness. When the tea substitute is in powder form, the preparation method includes the following steps: (1) Take the patchouli powder and pass it through a 10-mesh and a 50-mesh sieve at the same time. Continue to crush the coarse particles that cannot pass through the 10-mesh sieve and take the powder that is between the 10-mesh and 50-mesh sieves. (2) Grind and sieve the herbs in step (1) respectively; (3) Mix all the raw material powders evenly to obtain the final product. According to another aspect of the present invention, the above-mentioned medicinal and edible tea substitute for relieving heat and dampness is provided for the preparation of beverages for preventing heatstroke, especially for damp heat or yin heat. According to another aspect of the present invention, the above-mentioned medicinal and edible tea substitute for relieving heatstroke and dampness is provided for the application in the preparation of beverages that improve or alleviate heatstroke symptoms, especially damp heatstroke or heatstroke caused by dampness. The medicinal and edible tea provided by this invention can effectively relieve symptoms such as dizziness, heaviness of the body, joint pain, fatigue, chest tightness, nausea, dry mouth, bitter taste, abdominal pain, diarrhea, pale tongue, thick and greasy tongue coating, and floating and slippery pulse in people who are invaded by summer heat and wind-cold-dampness. Furthermore, this invention does not focus on inducing sweating, but rather on aromatic herbs to dispel dampness and turbidity. Through the ingenious combination of agastache and euphorbia, it prevents excessive sweating caused by pungent and dispersing herbs. Codonopsis and tangerine peel are added to prevent heatstroke from damaging the spleen and stomach. This serves two purposes: firstly, to strengthen the Qi of the middle Jiao (spleen and stomach), and secondly, to prevent the recurrence of heatstroke and dampness. Detailed Implementation The present invention will be further described in detail below with reference to specific embodiments. Unless otherwise specified, all raw materials are commercially available. Example 1 A medicinal and edible tea for relieving summer heat and dampness is prepared from the following ingredients: 10 grams of agastache rugosa, 5 grams of sesame, 10 grams of codonopsis pilosula, and 3 grams of dried tangerine peel. The above-mentioned traditional Chinese medicine composition can be prepared into an oral solution according to the following method: Soak the raw materials in 10 times their weight of water for 30 minutes, then heat to a boil and keep simmering for 1 hour. Separate the first decoction and the residue. Take the residue obtained after the first decoction, add water equivalent to 8 times the total weight of the raw materials, heat to a boil and keep simmering for 1 hour. Separate the second decoction and the residue. Combine the first and second decoctions to obtain an oral solution, which is a tea substitute. Example 2 A medicinal and edible tea for relieving summer heat and dampness is prepared from the following ingredients: 10 grams of agastache rugosa, 5 grams of sesame, 10 grams of codonopsis pilosula, and 3 grams of dried tangerine peel. It can also be ground into powder and made into dosage forms such as solid beverages according to the following preparation methods: (1) Take the patchouli powder and pass it through a 10-mesh and a 50-mesh sieve at the same time. Continue to crush the coarse particles that cannot pass through the 10-mesh sieve and take the powder that is between the 10-mesh and 50-mesh sieves. (2) Following the method in step (1), pulverize the licorice root, codonopsis root, and dried tangerine peel into powder and sieve them respectively; (3) Mix the powdered ingredients evenly, pack them into a packaging bag, and seal it. When needed, dissolve in 150mL of warm water and drink. Alternatively, it can be brewed with warm or hot water before drinking. In other embodiments, the amount of ingredients in a medicinal and edible herbal tea for relieving summer heat and dampness can be adjusted according to the patient's own condition, and these are all within the scope of protection of this invention. In other embodiments, the medicinal and edible tea of the present invention for relieving summer heat and dampness can also be made into tea bags, which can be steeped in hot water for at least 10-30 minutes before drinking, or boiled in water for at least 5-20 minutes before drinking. The herbal tea prepared in Example 1, which relieves summer heat and dampness, was used on subjects suffering from summer heat and dampness due to wind-cold-dampness. Information on gender, age, symptoms, and follow-up symptoms was collected from 30 subjects with summer heat and dampness due to wind-cold-dampness between August 5th and August 30th, 2024. Their main symptoms were scored. The 30 subjects were aged 24-66 years, with a mean age of 39.3 years; there were 15 males and 15 females. Before taking the herbal tea, their main symptoms included dizziness, heaviness in the body, fatigue, dry mouth, bitter taste, and loose or watery stools. The symptoms of 30 subjects suffering from summer heat and wind-cold-dampness invasion were compared before and after taking the herbal tea for relieving summer heat and dampness. The results showed that the average scores of dizziness, heaviness of the body, dry mouth, bitter taste, and loose or undigested stools were lower after taking the herbal tea than before (Table 1). This indicates that the herbal tea for relieving summer heat and dampness is significantly effective in alleviating the symptoms of dizziness, heaviness of the body, dry mouth, bitter taste, and loose or undigested stools in subjects suffering from summer heat and wind-cold-dampness invasion (P<0.05). The research results suggest that the medicinal and edible herbal tea of the present invention has a good effect on improving symptoms such as dizziness, heaviness of the body, dry mouth, bitter taste, and loose or undigested stools in subjects suffering from summer heat and wind-cold-dampness invasion. This indicates that the medicinal and edible herbal tea of the present invention has a good therapeutic effect on subjects suffering from summer heat and wind-cold-dampness invasion. Table 1. Statistical analysis of the effects of medicinal and edible herbal teas for relieving summer heat and dampness on the symptoms of subjects invaded by pathogenic factors of summer heat and wind-cold-dampness. The above descriptions are merely some embodiments of the present invention. Those skilled in the art can make various modifications and improvements without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
