Traditional Chinese medicine has always been said to be processed, and different processing methods can play a synergistic and attenuated role, and Ligustrum lucidum is no exception. At present, the commonly used processing methods of Ligustrum lucidum include steaming, wine processing and so on. Here is a brief introduction for everyone. First of all, let's understand the efficacy of Ligustrum lucidum.
Ligustrum lucidum is a dry and mature fruit of Ligustrum lucidum belonging to Oleaceae. It is sweet, bitter and cool, and has the functions of nourishing liver and kidney, improving eyesight and blackening hair.
Ligustrum lucidum is sweet and bitter in taste and cool in nature, and enters liver and kidney meridians. Has the effects of nourishing liver and kidney, nourishing yin, clearing away heat, cooling blood and improving eyesight.
"Materia Medica Rejuvenation" refers to "nourishing yin and kidney, invigorating qi and soothing liver". The Classic lists it as the top grade, saying that it is the main tonic, the five internal organs are safe, the spirit is nourished, all diseases are removed, and the body is fat and healthy for a long time, and the intellectual man is not old. " Ligustrum lucidum is good at tonifying kidney yin, and it is most suitable for people who need to tonify kidney and are afraid of getting angry.
Historically, there are many kinds of processed products of Ligustrum lucidum, such as steaming, wine, medicine juice, wine honey, salt and baking. But nowadays, most of them are made by wine.
The processing of Ligustrum lucidum began in the Song Dynasty.
Steaming method
Song Dynasty's Experience Book of Sores and Ulcers contained "steaming on rice", which was the original simple steaming method.
Wine making method
There are mainly wine steaming, wine soaking, wine frying and so on. Ming "Shen Nong's Herbal Classics": "Soak in wine for one day, steam thoroughly and dry in the sun". Ming's "Notes on the Medicine of Awakening First": "Wine mixing, nine steaming and nine drying".
Ming "Herbal Tongxuan": "Soak in wine, steam and dry". Ming, "(Revised) Explanation of the Medicinal Properties of Lei Gong's Processing": "Peeling in a cloth bag and soaking in wine for one night". Qing "Materia Medica": "Soak the wine for one night and steam it".
Medicinal juice system
There are Eclipta prostrata, Rehmannia glutinosa, black beans, white mustard, plantain and so on.
Ming's "Materia Medica" contains: "When the black fruit is harvested at the winter solstice, the skin will be cleaned in a cloth bag. Soak the wine for one night and let it dry in the sun. Grinding into pills, and decocting with Eclipta prostrata is wonderful; Mash and soak the wine, and put it into the pot with Radix Rehmanniae to cook well. "
Ming "Compendium of Materia Medica" said: "Ligustrum lucidum leaves are removed, soaked in wine all night, the skin is wiped off in a cloth bag, and dried into powder. When Eclipta prostrata comes out, take more stones and pound the juice until it is thick, which is as big as Maruko. "
For different processed products, the contents of Ligustrum lucidum ait. and oleanolic acid in raw Ligustrum lucidum ait., wine Ligustrum lucidum ait., vinegar Ligustrum lucidum ait. and salt Ligustrum lucidum ait. were determined. It was found that the order of the contents of Ligustrum lucidum ait. and three different processed products was salt Ligustrum lucidum ait. (1.997.5%) > salt Ligustrum lucidum ait. (1.600). The content of oleanolic acid in raw Ligustrum lucidum and three different processed products is in the order of wine Ligustrum lucidum (1.1202%) > salt Ligustrum lucidum (0.924 6%) > vinegar Ligustrum lucidum (0.9132%) > raw Ligustrum lucidum (0.899 8%).
Among them, oleanolic acid is an effective component of Ligustrum lucidum, which has the pharmacological effects of protecting liver, strengthening heart, reducing blood fat, lowering blood sugar and resisting inflammation.
The reason for the change of the two components is that Ligustrum lucidum glycosides gradually decrease with the increase of stewing time, and hydrolyze into the secondary glycoside salidroside, while oleanolic acid is a triterpene lipid-soluble component, which is easily soluble in alcohol, so the content of oleanolic acid after wine processing will be significantly higher than other processed products.
These two components are the main effective components of Ligustrum lucidum, and they are also the index components stipulated in China Pharmacopoeia. It can be found that the contents of these two components have changed after processing.
In clinical application, it is generally believed that raw Ligustrum lucidum is good at clearing liver and improving eyesight, nourishing yin and moistening dryness. It is mostly used for liver heat with red eyes and constipation due to yin deficiency and intestinal dryness.
Wine-made Ligustrum lucidum can alleviate its coolness and smoothness, and enhance the function of nourishing liver and kidney. It is mostly used for yin deficiency of liver and kidney, dizziness, tinnitus, premature graying of hair and blurred vision.
Salt-made Ligustrum lucidum can introduce medicine into the kidney, which has the strongest function of nourishing kidney yin, and is often used for soreness of waist and knees, dizziness and tinnitus due to kidney yin deficiency.
Therefore, when we use Ligustrum lucidum, it is best to properly process Ligustrum lucidum before use, so as to make full and reasonable use of Ligustrum lucidum according to our different purposes.
Chinese medicinal materials pay attention to processing, and various processing methods are effective to fully release the medicinal properties of Chinese medicinal materials. First of all, the raw and cooked processing methods of the same Chinese herbal medicine are different, and the medicinal properties are also different. The processed medicinal materials are also convenient for storage and transportation.
Ligustrum lucidum is a very common Chinese herbal medicine, and its price is low, at best, 1kg does not exceed 10 yuan. It is also called wax tree seed in our south.
The reason why Ligustrum lucidum was given a poetic name by the ancients was nothing more than to praise it for being restless in winter. Because of Ligustrum lucidum, if it is used as medicine, it needs to be picked in December. In the eyes of old Chinese medicine practitioners, Ligustrum lucidum is not afraid of cold. Therefore, it is considered as "essence of less yin". From Shaoyin to Taiyin, the degree of cold weather was originally described. In medical sage Zhang Zhongjing's original dialectics of six meridians, Shaoyin refers to the liver system and Taiyin refers to the kidney system.
The most important thing of Ligustrum lucidum lies in nourishing liver and kidney, and paying attention to nourishing liver and kidney yin. Most of the Ligustrum lucidum used by the ancients were steamed, which was not steamed in general, but steamed with wine.
In traditional Chinese medicine, many drugs need to be processed with wine. Naturally, I like to use the characteristics of rising wine to assist drugs and act on the human body. Take Ligustrum lucidum as an example. Ligustrum lucidum belongs to the subcategory of traditional Chinese medicine, and the so-called "everything will sink". And get cold in autumn and winter. From basic physics and common sense, we all know that "heat expands and cold contracts". In other words, Ligustrum lucidum will sink faster, and it will be excreted before it can make a difference in the human body.
If you want to keep Ligustrum lucidum in the human body for a longer time, you need to steam it with wine. You know, slower may be better!
Do you need to steam Ligustrum lucidum? Ligustrum lucidum can tonify liver and kidney; Clearing deficiency and heat; To improve eyesight, research shows that different steaming time has an effect on the content of oleanolic acid in Ligustrum lucidum. Compared with the results of steaming for 2 hours, 3 hours, 4 hours, 8 hours and 3 days, from the shape of Ligustrum lucidum, 4 hours and 8 hours are better, while steaming or stewing with wine is better. Considering the time efficiency, the actual processing time is 4 hours.
"China Pharmacopoeia" stipulates that Ligustrum lucidum should be stewed with wine or steamed with wine until the wine is completely absorbed or steamed. Local (Guangdong) regulations stipulate that the processing method should be "mixed with wine, moistened, steamed for 2-4 hours after the wine is completely absorbed, taken out and dried", but the technological parameters are not complete enough to guide the actual production. Other related documents also reported the processing methods, such as "soaking for 8 hours, steaming for 8 hours"; "30% yellow rice wine is moistened and steamed for 4 hours"; "Adding 20% yellow rice wine, no water, moistening 1h, steaming 10h" and so on, the technological parameters are uneven and incomplete.
The so-called "dew-up" of Ligustrum lucidum means that there is a layer of white powder on the outside of Ligustrum lucidum after steaming, which seems to be moldy. The causes of "dew-up" are: first, the steaming time is not enough, and second, the raw materials are pressed too tightly when they are put into the cage, and the steaming is uneven. Treatment method: the "exposed" Fructus Ligustri Lucidi is kneaded and dispersed, and then steamed until it is round, and it can be removed after 4 hours 1 hour. To prevent the "dew" of Ligustrum lucidum, it is necessary to ensure that the raw materials should not be pressed when they are in the cage, and continue for 5 hours after steaming.
Soak the fruits of Ligustrum lucidum harvested in the shade in early winter in wine for one day, steam them thoroughly and dry them in the sun, and take one catty and four ounces; Twelve taels of Eclipta prostrata collected in summer and dried in the shade; Mulberry harvested in late spring and dried in the shade, take twelve taels. Grind the three flavors into powder, add refined honey and make balls as big as wuzi. Every time you take seven or eight pills, light salt soup will give you an eye. If mulberry is picked in May and Eclipta prostrata is picked in August, juice and medicine can be pounded directly without adding honey. 8 Wind-heat and red eyes. Use an unlimited amount of Ligustrum lucidum, pound the juice and boil the paste, store it in a clean bottle, bury it in the ground for seven days, and take some eye drops.
