[Clinical Application] Treatment of chronic bronchitis: Rue has been made into various dosage forms and is widely tried. According to 835 observations using oral preparations, the total effective rate was 81.6% to 88.8%, of which the short-term control rate was 7% to 18.9% and the significant effective rate was 23.6% to 45.9%. 595 cases were given winter treatment. After half a year and one year of observation, the total effective rate was still 75.5%, which was higher in efficacy and lower in recurrence rate than the group without winter treatment. The symptoms of the relapsed cases were milder than in previous years, indicating that rue herb preparations seem to have the effect of consolidating the therapeutic effect. If the aerosol made from piperitone, the active ingredient in rue, is sprayed and inhaled, the therapeutic effect will be significantly improved. According to observations of 217 cases, the effective rate was 92%, the clinical control rate was about 20%, and the marked effect rate was 38% to 54%. The average onset time is 15 minutes, the average duration is 2 hours 45 minutes to 4 hours, and the longest is 16 hours. Practice has shown that rue herb preparations have obvious antiasthmatic effects, while their cough and expectorant effects are slightly less effective, and they also have certain antibacterial effects. Preparation and usage: 1. Rue extract tablets: 0.3 g per tablet, 2 to 3 tablets each time (if taken together with rue oil preparations, it can have a synergistic effect in treatment); 2. Rue oil capsules: each capsule contains 0.5 or 0.3 ml of rue oil, 2 to 3 capsules each time after meals; 3. Piperitone capsules: each capsule contains 0.5 or 0.3 ml of piperine, 1 to 2 capsules each time, after meals; 4. Sodium bisulfite piperitone tablets and pills: each tablet (capsule) contains 0.3 or 0.5 g of sodium bisulfite piperitone, 1 to 1.5 g each time. For patients with emphysema and acidosis, the acidosis should be corrected before taking this product, otherwise the effect will not be obvious. All the above preparations are taken three times a day, and one course of treatment is 10 days. ㈤ Rue aerosol: Each bottle contains 1.5 ml of piperitone (can be sprayed 150 times). Inhale 3 times in a row 3 times a day for 10 consecutive days. Side effects: Oral administration of rue oil and piperitone preparations may cause gastrointestinal reactions such as nausea, vomiting, and heartburn. In some cases, gingival swelling and pain and nosebleeds may occur. There are generally no gastrointestinal reactions when taking sodium bisulfite piperitone preparations; only a few patients experience dizziness, headache, palpitations, fatigue, diarrhea, and abdominal distension 2 to 6 days after taking the medicine, but they are all mild and do not affect continued medication. When using aerosol, some patients may experience temporary choking and coughing.
