It turns out that there are so many side effects of Ophiopogon japonicus

Ophiopogon japonicus is a common Chinese medicinal material in daily life. It contains many ingredients that are beneficial to the human body and has the effect of improving human immunity. Therefore, it is loved by people. Many people like to use Ophiopogon japonicus to make tea, but in fact Ophiopogon japonicus is not perfect. It also has side effects on the human body. Let us take a closer look at the side effects of Ophiopogon japonicus!

1. Ophiopogon japonicus has good safety in clinical use, and animal subacute toxicity experiments have shown that the drug has low toxicity.

2. There are reports that taking Ophiopogon japonicus can cause allergic symptoms such as nausea, vomiting, palpitations, irritability, erythema all over the body, and itching.

3. Ophiopogon japonicus is cold in nature and moist in nature, and has a good effect of nourishing yin and moistening dryness. It is suitable for diseases and symptoms with symptoms of yin deficiency, internal heat, dry cough and lack of body fluid. It is not suitable for diseases and symptoms of water dampness, cold dampness, phlegm turbidity and obvious qi deficiency caused by spleen deficiency and dysfunction of transportation and transformation. When using Ophiopogon japonicus as a tonic to replenish deficiency in clinical practice, attention should be paid to syndrome differentiation. Improper use will cause dampness and phlegm, and lead to adverse reactions such as excessive phlegm, dry mouth, and poor appetite.

4. Ophiopogon japonicus decoction has a sedative effect. Ophiopogon japonicus can also enhance the sedative effect of chlorpromazine, strengthen the hypnotic effect of sodium pentobarbital, antagonize the excitatory effect of caffeine, and delay the occurrence of convulsions, tonic convulsions and death caused by salpingo, but it cannot save animals from death.

5. It has an effect on the contraction amplitude of the myocardium. The guinea pig isolated heart perfusion method showed that small doses of total saponins and total amino acids of Ophiopogon japonicus can enhance myocardial contractility and increase coronary flow, while large doses can inhibit the myocardium and reduce coronary flow, but both have no effect on heart rate.

6. Ophiopogon japonicus will increase the weight of the spleen. ICR mice were intraperitoneally injected with Ophiopogon japonicus polysaccharide and ginseng total saponins, respectively, while the control group was given an equal amount of normal saline. After 7 consecutive days of administration, the animals were bled and killed, and their body weights and thymus and spleen weights were measured, and the thymus index and spleen index were calculated. Results Ophiopogon japonicus polysaccharide could significantly increase the spleen weight of mice.

7. Drinking too much Ophiopogon japonicus water can cause spleen and stomach deficiency and coldness. Ophiopogon japonicus can prolong the lifespan of fruit flies, suggesting that it can slow down the aging process. However, don’t think that the more Ophiopogon japonicus products you consume, the better. In fact, all products have two sides. Swimming tests show that the saponins, polysaccharides, and amino acids contained in Ophiopogon japonicus have obvious anti-fatigue effects. Ophiopogon japonicus is cold in nature, so it should not be used by people who have diarrhea, loose stools, greasy white tongue coating, and indigestion due to spleen and stomach deficiency. Children have incomplete digestive systems, so I don’t recommend them to drink it. Personally, I suggest that children with constipation can drink boiled white radish water, which has a better effect.
