Second, what are the pharmacological effects? Can you reduce the blood pressure?

1. Anti-inflammatory effect: honeysuckle has significant anti-inflammatory activity, and intramuscular injection can significantly inhibit foot swelling and pleural exudation in rats. Luteolin can cause thymus atrophy in young rats, indicating that luteolin can enhance the cortical function of the adrenal gland, which is related to its anti-inflammatory effect.

2. Anti-allergic effect: honeysuckle has a significant inhibitory effect on I-type allergic reaction. The mechanism of anti-allergic reaction is related to its ability to inhibit the release of allergic mediators, to competitively antagonize the spasmodic effect of SRS-An and histamine, and to directly make smooth muscle spasmolysis.

3. Antihypertensive effect: low concentration of honeysuckle can inhibit isolated heart, high concentration can excite guinea pig heart, accelerate heart rate, administration or intravenous injection has significant antihypertensive effect on anesthetized cats, and high dose can reduce shock level. a higher dose can cause the cat to die of shock.

4. Other effects: luteolin has antispasmodic effect on isolated rabbit small intestine, guinea pig tracheal smooth muscle and ileum. Lonicera japonica has the effects of antibacterial, antitussive, expectorant and antiasthmatic, antispasmodic effect on isolated rabbit small intestine, mild diuretic effect and increased sodium excretion.
