It is not only a medicine, but also a health product, which can be taken for a long time. In recent years, I have also taken acanthopanax senticosus tablets intermittently, and I feel that it has certain curative effect. ""However, I later saw in the Adverse Reactions of Traditional Chinese Medicine and its Preparations that Acanthopanax senticosus injection had toxic and side effects, mainly rashes and anaphylactic shock. In addition, it also mentioned serious eye reactions such as severe blurred vision, diffuse edema in both eyes, and unclear macular area. " "I think, acanthopanax senticosus tablets and acanthopanax senticosus injection, ingredients are acanthopanax senticosus, will have the same side effects? I didn't have the first two side effects listed in the book, and it wasn't very terrible. What is terrible is the impact on the eyes in the third reaction, because it is difficult to detect, and it is too late to detect it. " "Can Acanthopanax senticosus tablets be taken for a long time, and does it have adverse reactions to the eyes?" The acanthopanax senticosus asked by readers is actually a commonly used Chinese medicine, which is also known as the root and rhizome of acanthopanax senticosus, tiger shackles, spiny crutches and grass. The record of Wujia was first seen in Shennong Materia Medica Classic, which was listed as the top grade. There are many varieties of ancient medicinal acanthopanax bark, including acanthopanax senticosus and other plants of acanthopanax. Acanthopanax senticosus is bitter, slightly cold and non-toxic. Traditional Chinese medicine believes that it has the functions of invigorating qi and spleen, tonifying kidney and calming nerves, expelling wind and dampness, strengthening bones and muscles, promoting blood circulation and removing blood stasis, nourishing the middle energizer and essence, strengthening the mind and intelligence, strengthening the stomach and promoting diuresis. The medicinal value of acanthopanax senticosus has been highly praised by ancient materia medica. In Compendium of Materia Medica, there is a saying that "it is better to have a handful of five herbs than a car full of gold and jade", and "the article can make wine into its taste, buy grass with gold, and don't say it is expensive". Modern research has confirmed that Acanthopanax senticosus contains many active ingredients such as acanthopanax senticosus, polysaccharides, etc., which have pharmacological effects such as anti-aging, anti-fatigue (the anti-fatigue effect of Acanthopanax senticosus is stronger than that of ginseng), anti-cancer, regulating nervous, endocrine and cardiovascular functions, improving the body's resistance to physical, chemical, biological and other harmful stimuli, etc., and are used in neurasthenia, insomnia, hypertension, coronary heart disease, cerebral infarction, cerebral arteriosclerosis, climacteric syndrome. At present, there are many kinds of acanthopanax senticosus preparations in the medical market, mainly including tablets, injections, syrups and capsules. Oral acanthopanax senticosus tablets, syrups, capsules, etc. generally have no adverse reactions, but acanthopanax senticosus injection is not. When acanthopanax senticosus injection is used, it is usually added to 0.9% physiological saline or 5% glucose injection for intravenous drip. The medical literature reported that some patients had skin rash, dizziness and even anaphylactic shock. In addition, Acanthopanax senticosus injection can also cause eye damage such as blurred vision, as described in the "Ceremony of Adverse Reactions of Traditional Chinese Medicine and its Preparations" mentioned in this reader's letter. However, there is no need for us to be afraid of acanthopanax senticosus injection, because there are only a few patients with side effects. As long as acanthopanax senticosus injection is used reasonably under the guidance of a doctor, possible side effects can generally be avoided or eliminated. In addition, we can't simply infer that acanthopanax senticosus tablets have the same side effects as the main components of injection, because the reaction of drugs in digestive tract and blood is different. Finally, no matter which preparation of Acanthopanax senticosus is, it is a medicine. Any drug has two sides when taken for a long time, so it must be taken under the guidance of a doctor.
