Description

Technical Field

[0001] The invention relates to the technical field of traditional Chinese medicines, and in particular to a traditional Chinese medicine composition for improving amnesia and a preparation method thereof. Background Art

[0002] Forgetfulness refers to a temporary obstacle in the brain's thinking and retrieval abilities, and is a clinical disease with memory loss, forgetfulness and other brain function impairment as the main manifestations. Modern medicine calls amnesia a temporary memory disorder, and Chinese medicine calls it "amnesia". The disease was first recorded in the Yellow Emperor's Classic of Internal Medicine, and was called "forgetfulness" or "good forgetfulness". Qianjin Fang and Wai Tai Mi Yao called it "good forgetfulness". The term "forgetfulness" first appeared in Taiping Shenghui Fang. Lei Zheng Zhi Cai describes amnesia as: "Forgetfulness is a sudden forgetfulness, and it can't be recalled no matter how hard you try." Chinese medicine believes that it is mainly caused by various reasons, such as insufficient brain marrow, malnutrition of brain marrow, or disturbance of the spirit, resulting in memory loss and forgetfulness. At present, when treating amnesia, most of the prescriptions are formulated with tonifying the kidney, replenishing essence and benefiting the marrow, but the deficiency of kidney qi and kidney essence is the main cause, but the deficiency of kidney qi and kidney essence is caused by many reasons, and simply tonifying the kidney and replenishing essence cannot achieve a good therapeutic effect.

[0052] When used, the above medicine is divided into bottles, ml per bottle.

[0053] Embodiment 4:

[0054] Fifteen volunteers who were diagnosed with amnesia through Chinese Internal Medicine were recruited, including eight males and seven females, aged between 35 and 55 years old. People with cerebral arteriosclerosis, cerebral infarction and other organic brain diseases were excluded.

[0055] The above volunteers used the oral liquid prepared in Example 3 to improve the treatment of amnesia, three times a day, 1-2 bottles each time, for 2 consecutive months, and the efficacy was statistically analyzed.

[0056] The TCM symptom scores before and after taking the medicine were statistically analyzed.

[0057] The statistical standards for TCM symptom scores are as follows:

[0058] Forgetfulness: Normal 0 points; Occasional forgetfulness 2 points; Memory weakened, but still able to recall 4 points; Occasional forgetfulness, but difficult to recall 6 points;

[0059] Insomnia: Normal: 0 points; less than 2-3 hours of sleep per day; difficulty falling asleep: 2 points; sleeplessness all night: 3 points;

[0062] Recovery: amnesia symptoms or signs basically disappear, and the score decreases by ≥90%;

[0063] Markedly effective: amnesia symptoms or signs are significantly improved, 90> points are reduced by ≥70%;

[0064] Effective: amnesia symptoms or signs have improved, 70> points reduced by ≥30%;

[0065] Ineffective: no significant improvement in amnesia symptoms or signs, and the score reduction is less than 30%;

[0066] The results showed that 2 people were cured, 4 people were significantly effective, 5 people were effective, and 4 people were ineffective. The effective rate ((cured + significantly effective + effective) * 100% / total number of people) was 73.33%.

[0067] Embodiment 5:

[0068] Case 1: Ms. Li, 57 years old, female, was reminded by her family that she often lost things in the past three months. For example, she often couldn't remember whether she locked the door when she went out, or forgot to take things when she bought them, and she had difficulty concentrating. After taking the oral liquid prepared in Example 3 of the present invention, three times a day, 1-2 bottles each time, after taking it for 2 consecutive months, she felt that her concentration was significantly improved, and the frequency of losing things was greatly reduced.

[0069] Case 2: Ye, male, 52 years old, often felt that he could not concentrate when reading books and newspapers in the past six months, and was reminded by many people to repeat the same words frequently, or suddenly forgot what he said when speaking. He felt very troubled and was later diagnosed with amnesia. After taking the oral liquid prepared in Example 3 of the present invention, three times a day, 1-2 bottles each time, after taking it for 2 consecutive months, he felt that his concentration was significantly improved and his amnesia symptoms were improved. For example, the frequency of repeating the same words to the same person was significantly reduced.
