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.
How much echinacea do I need to treat the flu?
Depending on the product, different echinacea dosages are advised. The most frequently prescribed medication in the US is a liquid extract of the E. purpurea root, which is typically dosed at 3 mL every three to four hours for the first one to two days of upper respiratory sickness and then three times per day for the following week. Patients utilizing echinacea tea (prepared from the root of E. angustifolia or E. purpurea) must start with greater doses, usually 6 to 8 oz four times per day for the first two days before reducing it to once or twice per day on days three to seven.
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.
Does echinacea actually work?
Mixed findings have emerged from studies. Echinacea extracts do appear to affect the immune system, your body’s line of protection against pathogens. According to research, it boosts the quantity of white blood cells, which fight illnesses. The herbal medicine had a very little advantage in avoiding colds, according to an analysis of more than a dozen research that was published in 2014.
However, neither children nor adults who took echinacea for a cold reported any relief from it in two trials supported by the National Center for Complementary and Integrative Health.
However, because different studies examine different echinacea varieties and potencies as well as various plant or root portions, it might be challenging to compare the findings of several studies. There’s a chance that certain variations are superior to others. Additionally, it’s probable that the herbal cure will work against some but not all of the more than 200 cold-causing viruses.
Echinacea and existing illness: Does it work?
People frequently look for all-natural cold treatments and immune boosters during the cold and flu season. Colds are said to be both prevented by and cured with echinacea for many years. However, there is conflicting data in support of the herbal supplement, and it is challenging to examine due to its various formulations.
the title “Nearly ten species of flowering herbs are referred to as echinacea, and one or more of these species are used in echinacea supplements. Either the plant’s above-ground components or its underground roots can be used to create them (or both). Due to all this variation, there is dispute among professionals regarding the advantages of echinacea.
“According to Dr. Ronald Turner, a professor of pediatrics at the University of Virginia School of Medicine, his 2005 study, which was published in the New England Journal of Medicine, “found no evidence for an effect of echinacea on common cold diseases.” Turner and his associates used a variety of echinacea preparations, prepared from the Echinacea angustifolia species’ roots, to treat participants in that study. When it comes to preventing colds or lowering their severity, the echinacea supplements did not outperform the placebo.
According to other professionals, echinacea may be beneficial. “According to Kelly Kindscher, a professor of environmental studies at the University of Kansas and the author of an echinacea textbook, echinacea is well-liked because it does workâat least for some people. Kindscher claims that while some clinical studies have not demonstrated the efficacy of echinacea, others have discovered advantages.
In a 2010 study, echinacea was compared to a placebo and no treatment at all in the Annals of Internal Medicine. It discovered indications that echinacea performed better than both in terms of shortening the duration of the common cold, although these advantages were not statistically significant. There was no proof that echinacea could stop colds, according to a 2006 assessment. However, it did uncover evidence that suggests products containing the species Echinacea purpurea may shorten the duration and symptoms of a cold.
A 2014 analysis, however, acknowledged echinacea with “just marginally effective in protecting people from colds. Echinacea received a more enthusiastic recommendation in a 2015 evaluation, which found that it may lower a person’s risk of colds by 35%. How? Dr. Andreas Schapowal, the initial author of that 2015 review and a former lecturer at Hannover Medical School in Germany, speculates that echinacea may function by boosting the reaction of natural killer cells and other immune system fighters as well as by blocking the action of specific viral proteins.
Brief overview
However, no studies utilizing Echinacea in the prevention or treatment of illnesses similar to COVID-19 have been found. Current research 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.
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.
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.
