Preparation method of external medicine for benign paroxysmal vertigo

Abstract

The invention discloses a preparation method of an external medicine for benign paroxysmal vertigo, aiming to solve the problem of treatment of the benign paroxysmal vertigo. The preparation method comprises the following steps: extracting volatile oil from cynachum uilfordii hemsl, lycopodium, wormwood, asparagus fern and bulbophyllum Inconspicuum maxim for later use and reserving herb residues; mixing and extracting mole cricket, spiny raspberry root, carex baccans, cutworm, cruciate buchnera herb, wallichiana, beheaded and the herb residues obtained from the step 1 with water; carrying out vacuum concentration on the obtained extract liquid; adding ethanol to the concentrated liquid, and standing under refrigeration; taking supernate, filtering, and recovering ethanol from filtrate; adding 0.5% of powdered activated carbon to the concentrated filtrate, stirring evenly, boiling, cooling to 50 DEG C, and carrying out suction filtration through a 0.4micron filter film; and adding glycerinum to 20% of filtrate, mixing evenly, spraying the volatile oil obtained from the step 1, mixing evenly and sub-packaging. A clinical experiment proves that the external medicine has the characteristics of good curative effect and relatively high safety on treatment of benign paroxysmal vertigo, and is worthy of clinical application and popularization.

Description

technical field [0001] The invention relates to the field of traditional Chinese medicine, in particular to a preparation method of an external medicine for benign paroxysmal vertigo. Background technique [0002] Benign paroxysmal positional vertigo (BPPV) is a common disease in neurology clinics, accounting for 20% to 40% of all vertigo cases. The cause of the disease lies in the tiny particles attached to the enlarged part of the semicircular canal in the inner ear, the "ampulla". Under the action of gravity, it moves away from the ampulla to form a lymphatic flow away from the ampulla, which causes the crest to shift and cause vertigo and nystagmus. [0003] There is no effective neurological conservative treatment for BPPV, and “manipulative reduction” is often used, that is, the patient is changed 5 positions by manipulation, so that the canal stone fragments of the posterior semicircular canal and superior semicircular canal enter the utricle through the common crus....

Problems solved by technology

However, in clinical practice, the reduction effect of horizontal semicircular canal otoliths is worse than that of posterior semicircular canal; the reduction effect of horizontal semicircular canal crest calculi is even worse. The calcium-containing particles deposited at the top of the crest are not the same as the aforementioned canal stones: ①The calcium-containing particles deposited on the top of the crest are a kind of basophilic inflammatory granule group, not the simple calcium carbonate particles in the semicircular canal stones, so they aggregate Strong, strong adhesion, not easy to flow; ② patients with semicircular canal stones have a latency period of 3 to 40 seconds after the vertigo is stimulated in the head position, while vertigo in the ampullary ridge stones stimulates the posture immediately and has no latency period. , the latter has a strong feeling of vertigo, which leads to the failure of manual reset

Therefore, it has been reported in the literature that the effective rates of manipulative reduction therapy for "semicircular canal stones" and "ampullary crest stones" were 92% and 63%, respectively, and 41% of patients with "ampullary crest stones" were unable to resist manual reduction therapy. Changes in head position during treatment leading to discontinuation of treatment
