Description

Migrainous Chinese medicine composition of a kind of treatment and preparation method thereof

Technical field

The present invention relates to the migrainous medicine of a kind of treatment, be meant the migrainous Chinese medicine composition of a kind of treatment especially, the invention still further relates to the preparation method of this Chinese medicine composition.

Background technology

Migraine is a kind of the most common clinically vascular headache, is head vasomotor dysfunction and cerebral cortex functional disorder, or the caused clinical syndrome of the temporary change of some humoral substance.Migraine is the periodical attack disease that a class has family's morbidity tendency, shows as the inclined to one side side pulsatile headache of paroxysmal outbreak, and the companion feels sick, vomiting machine photophobia, can be with nerve, moral function obstacle before headache takes place or during outbreak.Migraine is a common frdquently encountered disease, and is mainly in adolescence (sickness rate was the highest in 20～29 years old).In recent years, along with the progress of society and the raising of people's living standard, the change of dietary structure, the quickening of work and study rhythm and the pollution of air ambient are suffered from migrainous patient day and are more increased.According to relevant bibliographical information, it is about 9% that the average attack rate male of this disease in the various countries crowd is grown up, and the women is grown up about 16%.Domestic sickness rate is then higher, and the inland north sickness rate in summer is up to 55.3%, and southern area is wet partially warm spring, and spring, sickness rate was also high to 46.3%.Morbidity women's ratio is higher than the male, and men and women's ratio is 1: 3.5, and the aeg falls ill normal relevant with menstruation.Owing to have the above-mentioned symptom during except that morbidity, outbreak back most of patients has tired, drowsy, has seriously hindered patient's work and study and rest.Migrainous control comes into one's own day by day.

At present, doctor trained in Western medicine still fails to illustrate fully to the cause of disease of primary disease, the treatment migraine still lacks ideal medicine, and the traditional Chinese medical science is to this sick existing comparatively mature theory basis and clinical treatment experience, so the migrainous medicine of treatment by Chinese herbs has good development prospect, current main medicine is: kinds such as the six channels headache tablets, rhizoma gastrodiae tablets for relieving headache, armillaria mellea accreting with Rhizoma Gastrodiae sheet, wind syndrome of head pain ball, and less for the Chinese patent medicine kind of selection of clinical.Because of migrainous common property, multiple, need regular medication treatment, again so the huge market demand of this quasi drugs.Adopt the migrainous effect of wind syndrome of head pain pill for curing better clinically, its prescription is as follows with preparation method: [prescription] Radix Angelicae Dahuricae 420g, Rhizoma Chuanxiong 60g, green tea 30g.[method for making] above three flavors are ground into fine powder, sieve, and mixing is used water pill, dries or cold drying, promptly.[usage and consumption] is oral, a 6～9g, 2 times on the one.According to Chinese medical discrimination, the card that this side controlled, be because of venation numbness resistance jerk urgency or muscle arteries and veins lose support due to, and many with the liver failing to maintain the normal flow of QI, hold under the arm disturb on the heresy relevant.Excessive rising of liver-YANG, then headache and bloated, dizzy bitter taste, dysphoria with feverish sensation in the chest palms and soles; Disturb on expectorant is turbid, the unconsciousness of then having a headache, chest distress, the heavy body of limb is tired; Control suitable wind-expelling pain-stopping, promoting flow of QI and blood.Be monarch with the Radix Angelicae Dahuricae in the side, its acrid in the mouth is warm in nature, kind expelling wind and removing dampness, understand things pain-stopping.The Rhizoma Chuanxiong acrid in the mouth is warm in nature, the function promoting blood circulation to remove blood stasis, and activating QI to alleviate the depression has the merit of diffusing wind pain relieving, is the key medicine for the treatment of blood disorders.The same usefulness of two medicines, dispelling wind looses evil, and the expectorant stasis of blood is ruled together.Green tea bitter in the mouth, sweet cool in nature is aided with the refresh oneself, and relieving restlessness is reduced phlegm; All medicines match, and the ailment said due to cold or exposure of the five internal organs is all dispelled, and stagnation of QI blood stasis removes to the greatest extent.

But the former dosage form of wind syndrome of head pain ball is the watered pill, the medical material un-extracted, bioavailability is low and dose big, and (one time 6～9g), former dosage form quality standard has only the physicochemical identification of coumarin substances in the microscopical identification and the Radix Angelicae Dahuricae, far can not reach present requirement to drug standard.The present inventor is through to this side's conscientiously research, and the dosage form that exploitation makes new advances at the safety that guarantees medicament and effectiveness simultaneously, strengthens the bioavailability of material medicine, so that its drug effect is higher, dose reduces, carries, use, accumulating be more convenient.
