One of the most widely used herbs in America right now is echinacea. Native Americans gave the medicinal herb echinacea its name because of the prickly scales that mimic the enraged hedgehog’s spines on its enormous conical seed head (echinos is Greek for hedgehog).
Native Americans may have used echinacea for more than 400 years to treat wounds and illnesses as well as a general “cure-all,” according to archaeologists who have discovered evidence of this. Echinacea has been used historically to treat blood poisoning, diphtheria, syphilis, malaria, and scarlet fever. Although this herb was widely used in the 18th and 19th centuries, its use started to diminish in the US once antibiotics were developed. In Germany, echinacea preparations gained popularity during the course of the 20th century. In actuality, Germany has been the site of the majority of echinacea scientific research.
Today, individuals take echinacea to lessen the severity of the common cold and flu and to lessen symptoms including fever, coughing, and sore throats (pharyngitis). Echinacea is another plant that many herbalists advise taking to help the body fight infections and strengthen the immune system.
General Uses
Echinacea may include active ingredients that improve immunological function, ease pain, lessen inflammation, and have hormonal, antiviral, and antioxidant effects, according to a number of laboratory and animal studies. Because of this, qualified herbalists may suggest echinacea as a treatment for slow-healing wounds, ear infections, athlete’s foot, sinusitis, vaginal yeast (Candida) infections, ear infections, otitis media, hay fever, and slow-healing wounds. Echinacea and cichoric acid may help suppress colon cancers, according to preliminary laboratory studies. According to one study, using echinacea extract before contracting the herpes simplex virus (HSVI) may have an antiviral effect on the recurrence of cold sores.
Common Cold
It is debatable if echinacea aids in the prevention or treatment of the common cold. According to certain research, the herb can hasten your recovery. Others claim that echinacea has no effect at all on a cold. According to several clinical studies, persons who take echinacea as soon as they start to feel unwell have milder colds and experience less symptoms than those who do not. In a study of 95 patients who had fever, runny nose, scratchy throat, and other early signs of the flu and cold, it was discovered that those who drank many cups of echinacea tea daily for five days felt well more quickly than those who drank tea without the herb.
Echinacea decreased cold risk by 58 percent and cold duration by 1 to 4 days, according to a study of 14 clinical trials. Some experts, however, contest these results, arguing the research had a number of flaws. Clinical trials have used a variety of echinacea formulations. It’s crucial to get a high-quality echinacea supplement and to start taking it as soon as a cold starts, numerous times each day for the first few days. For advice, consult your health care practitioner.
Is it safe to consume echinacea daily?
A Cochrane Library systematic review was released by researchers in 2006. A systematic review is when a team of professionals compiles all the information available on a specific topic. Then they examine it to determine whether there is any supporting evidence. 13 trials were examined in the review by the researchers. The studies investigated whether echinacea could be used to treat and prevent the common cold.
Some studies suggested that it might shorten the duration of colds and ease symptoms. Others, though, proved that it was ineffective.
According to the review, there is no proof that echinacea can shield you from the common cold. More study of how echinacea might combat infections was advised. to find out more about its side effects, as well.
In 2010, a study examined how successfully echinacea root treated persons who were already congested. It was discovered that ingesting echinacea had no effect on how long colds lasted.
Over 700 participants were the subject of a study in 2012 by researchers. They discovered that daily echinacea users for at least 4 months saw few adverse effects and fewer colds.
In 2014, researchers conducted a further Cochrane review. They discovered that the echinacea products sold on the market vary greatly.
Additionally, they discovered that 10 to 20 out of every 100 persons may be less likely to have a cold as a result of certain varieties (10 percent to 20 percent ).
The researchers believed that this was a little effect and that there was conflicting data to back it up. This is so because various echinacea preparations were employed in the experiments.
Echinacea’s effects on the immune system
Evidence suggests that echinacea may strengthen the immune system, aiding the body’s defense against viruses and illnesses ( 33 ). Echinacea can reduce the duration of the common cold, diminish the intensity of its symptoms, or even prevent it, according to numerous research ( 33 ).
Do viruses benefit from echinacea?
Commercial Echinacea extracts generally have poor characterization and standardization, which is a problem shared by many other herbal products. Therefore, diverse commercial sources with distinct chemical compositions, sourced from various species and plant sections, may exhibit a variety of bioactivities, or in some cases, very little bioactivity [17]. As a result, research investigations, particularly clinical trials, have produced erratic outcomes. The assay methods should take this requirement into account in order to verify that any antiviral activity found in a herbal preparation is actually significant, meaning the extract should be able to inactivate a large amount of virus at a realistic non-cytotoxic dosage.
Early studies on the antiviral properties of echinacea [18] suggested that a variety of methanol and aqueous extracts from E. purpurea could be able to partially shield cultured cells from infection by the influenza A virus, herpes simplex virus type 1, or vesicular stomatitis viruses. Although the potential for virucidal activity was not mentioned, this implied an intracellular inhibition.
In whom should echinacea not be taken?
Consult your doctor before using echinacea if you regularly take other medications. Additionally, if you smoke, use illegal substances, drink alcohol or caffeine-containing beverages, you should disclose this to your doctor. These might impact how echinacea functions.
If you have an autoimmune ailment (like lupus), an infection with the human immunodeficiency virus (HIV), or acquired immunodeficiency syndrome, echinacea may not be beneficial to you (AIDS). Before beginning to use echinacea, you should discuss with your doctor if you are pregnant or nursing.
Echinacea allergy risk may be increased if you have a history of allergies to daisies, ragweed, marigolds, chrysanthemums, or other related plants.
Brief overview
However, no studies using Echinacea in the prevention or treatment of conditions similar to COVID-19 have been found. Current evidence suggests that echinacea supplementation may reduce the duration and severity of acute respiratory tract infections. There were not many side events reported, indicating the relative safety of this herbal medication. Clinical studies have shown that Echinacea lowers levels of immunological molecules associated with cytokine storm, despite the fact that it might boost immune activity, which raises concerns that it can worsen over-activation of the immune system in cytokine storm.
Verdict
When given at the earliest sign of infection, Echinacea supplements may help with the symptoms of acute respiratory infections (ARI) and the common cold. No trials employing Echinacea in the prevention or treatment of illnesses like COVID-19, however, have been found. When taken at the outset of symptoms, Echinacea may lessen the intensity and/or duration of ARI, according to earlier research. E. purpurea or a mixture of E. purpurea and E. angustifolia having standardized levels of active components were employed in trials claiming benefit.
Echinacea use hasn’t been associated with many side effects, which suggests that this herbal remedy is generally harmless. No human studies using echinacea for up to 4 months could be found that showed cytokine storm symptoms.
The results were largely consistent with a reduction in the pro-inflammatory cytokines that are involved in the progression of cytokine storm and Acute Respiratory Distress Syndrome (ARDS), factors that are highly significant in the death of COVID-19 patients when looking at all human trials that reported changes in cytokine levels in response to Echinacea supplementation. Even though there isn’t any research on the therapeutic benefits of echinacea in the treatment of cytokine storms right now, this evidence shows that more study is necessary.
Echinacea – is it an antibiotic?
There is no risk of the emergence of Echinacea-resistant bacteria because the process by which infections are treated with Echinacea is entirely distinct from that of antibiotics. Native Americans have employed the herb echinacea from the southwestern plains of North America for a number of ailments for generations.
How can I swiftly strengthen my immune system?
Having a robust immune system includes using vaccines, which provide us the best chance to defend ourselves against dangerous diseases.
Although your immune system is already intelligent, vaccinations help it become even more so by teaching it how to identify and combat particular diseases. Your immune system will learn much more safely through vaccination than through direct contact with these dangerous pathogens.
It’s crucial to stay up to date with all advised immunizations, particularly your annual flu shot and COVID-19 booster.
Introduction
Popular herbal remedy echinacea is made from the flowering plant echinacea purpurea, which is indigenous to the eastern United States east of the Rocky Mountains. Echinacea has traditionally been used to treat and prevent upper respiratory conditions like the common cold. The use of echinacea has been linked to isolated cases of elevated serum enzyme levels and clinically obvious liver damage, despite the fact that it is typically well tolerated with few and moderate side effects.
Background
Echinacea (ek” I nay’ sha), also known as American coneflower and a perennial plant native to North America, is the source of this widely used herb. To manufacture teas, juices, extracts, capsules, or tablets, the echinacea plant’s aerial portions and roots are employed, either fresh or dried. The primary use is for the treatment or prevention of upper respiratory infections, but it is also said to have other uses, including the improvement of immune function, protection against other viral, bacterial, and fungal infections, and the relief of anxiety, migraine headaches, dyspepsia, skin rashes, and bee stings. There are at least 9 different species of echinacea, and their therapeutic properties can vary. The most widely used extracts come from Echinacea purpurea, pallida, and angustifolia, which are used in thousands of commercial herbal and nutritional products. Although the exact composition of the active components in echinacea is unknown, plant extracts do contain a variety of polysaccharides, volatile oils, caffeic and ferulic acid derivatives, flavonoids, alkamides, and polyenes. Mixed findings have been found in controlled studies of echinacea in the prevention and treatment of common upper respiratory infections, and the majority of systematic reviews have come to the conclusion that there is little proof of its therapeutic efficacy. Echinacea extracts, however, have consistently been reported to be well tolerated and free of serious side effects. Minor stomach discomfort and skin rashes have been the most often reported side effects. Rare allergic responses have been reported, including urticaria, angioedema, and anaphylaxis.
Hepatotoxicity
Echinacea by itself has not been connected to liver injury in several controlled trials, either in the form of temporary serum enzyme increases or clinically obvious acute liver impairment. Toxic hepatitis and high serum aminotransferase levels have been linked to echinacea, according to summary data from national registries of adverse reactions. However, there have been sporadic case reports of clinically evident liver impairment with jaundice. There were little data about the liver damage, but according to two published accounts, hepatitis with jaundice appeared one to three weeks after commencing echinacea extracts, with moderate jaundice, noticeable ALT and AST rises, and a swift and complete recovery upon discontinuing. One of the cases had autoimmune characteristics, but neither instance displayed hypersensitive characteristics (fever, rash, lymphadenopathy or eosinophilia). It is unknown whether the cases were caused by a specific species, a method of preparation, or product contamination because of the variety in the components of echinacea products.
Echinacea and kidney health
If you have renal illness, stay away from herbal medications because they can increase blood pressure.
Some, like St. John’s Wort (for poor mood), may interfere with renal disease medications.
Before using some, such as the cold and flu treatment echinacea, consult with your doctor or pharmacist because they may have an adverse effect on kidney function.
Another issue is that the amount of the active ingredient in herbal remedies can vary significantly across brands (and even between batches of the same brand). This makes it challenging to anticipate how potent a dose will be.
Does echinacea benefit the lungs?
There is limited proof that Echinacea helps treat other ailments, and researchers have not yet established if it might lessen the severity of a cold.
The authors of a review discovered in 2011 that various echinacea extracts may aid in the treatment of viral respiratory infections. They do, however, make the point that the lack of uniformity among Echinacea products may prevent consumers from discovering efficient treatments.
A commercial medicine containing Echinacea extract may help prevent severe respiratory illnesses brought on by coronaviruses, according to a study from 2020.
However, other researchers point out that this little study did not examine how the product affected the virus that causes coronavirus illness 19 (COVID-19).
In addition, the product had not been tested on actual humans but rather solely on cell lines and viral particles. Additionally, the study was not peer-reviewed, and it in no way suggests that echinacea can treat COVID-19.
The scientists who issued the warning also mention that autoimmune disease sufferers may be at risk from the product.
There is no proof that Echinacea or any other herbal medication component can treat COVID-19 or other severe respiratory disorders.
