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.
What advantages does echinacea possess?
Echinacea extracts may inhibit the growth of cancer cells and even cause cancer cell death, according to experiments conducted in test tubes (25, 26).
An extract of Echinacea purpurea and chicoric acid, which is naturally present in echinacea plants, was demonstrated in one test-tube investigation to cause cancer cell death (25).
In another experiment, echinacea plant extracts (Echinacea purpurea, Echinacea angustifolia, and Echinacea pallida) destroyed colon and pancreatic cancer cells in test tubes by inducing apoptosis, or regulated cell death (26).
It is thought that the immune-stimulating components of echinacea cause this effect (27).
Conventional cancer medicines like doxorubicin were once thought to interact with echinacea, but more recent investigations have found no evidence of this (28, 29).
Echinacea has been demonstrated to enhance skin health, blood sugar control, anxiety, and immunity. It might even possess anti-cancer qualities. However, there hasn’t been much human-based study on these advantages.
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.
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.
Why echinacea shouldn’t 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.
Adult
Take echinacea three times daily for the first ten days of a cold, flu, upper respiratory infection, or bladder infection to stimulate the immune system generally.
Echinacea should NOT be taken on an empty stomach. Take it with food or a big glass of water instead.
What results from daily echinacea use?
The United States and Canada are home to the blooming plant echinacea. Additionally known as coneflower. It belongs to the family of plants known as daisies. For many years, echinacea has been used as a herbal treatment. The viruses that cause colds, sore throats, and the flu are now frequently prevented or treated with it.
Most drug stores and health food stores carry echinacea products. It is available as teas, pills, liquid extracts, capsules, or dried plants. It is one of the most widely used herbs in the country.
Path to improved health
Echinacea is frequently used as a dietary supplement to treat infections like the common cold. They contend that it strengthens the immune system. This improves the body’s ability to combat the infection. As a result, the illness might not persist as long. When feeling well, some people use it to avoid getting sick.
Consult your primary care physician before using echinacea to treat a cold or the flu. Make sure to conduct your study as well. Before being sold, dietary supplements do not require FDA approval. The components in some supplements may not be what is listed on the label. Look for a business that quality tests their goods. You will then be certain that you are acting appropriately.
Pay close attention to the package label. Echinacea is available in a wide range of doses and strengths. Additionally, it may be combined with other nutrients. Observe the instructions on the packaging. Take only the prescribed amount. It can be hazardous to take more than is advised.
The majority of companies advise against eating echinacea on an empty stomach. They advise drinking a lot of water or eating before taking it. Echinacea shouldn’t be taken for more than a few weeks. Long-term safety has not been sufficiently investigated.
Before taking echinacea or any supplements, consult your doctor. If it will conflict with any other medications you take, he or she can let you know. They can also suggest the appropriate dosage for you.
Keep all herbal products out of young children’s sight and reach. To prevent them from losing their potency, keep them in a cool, dry area. Avoid keeping them in restrooms, which tend to get warm and muggy.
Does it work?
On the impact of echinacea on the common cold, numerous studies have been conducted. Researchers have not yet discovered concrete proof of its efficacy. They don’t think that taking it as soon as a cold hits will make it go away faster. Taking it when you are healthy may somewhat lower your risk of contracting a cold.
What are the side effects?
Minor adverse effects are possible with echinacea. These symptoms can include nausea, dizziness, and a queasy stomach. Allergic reactions such as redness, swelling, and breathing difficulties are considered serious adverse effects. It may exacerbate asthmatic symptoms. Inform your doctor as soon as possible of any negative effects you have.
Daisy family plants can cause allergy reactions in some people. These could include chrysanthemums, marigolds, ragweed, daisies, or other flowers. This could increase your chance of experiencing an allergic reaction to echinacea.
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.
Does echinacea really work as it claims to?
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.
