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.
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.
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.
What dosage of echinacea is recommended for a cold?
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.
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.
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.
Positive effect on the immune System
Numerous studies have revealed that this plant may support your immune system’s ability to fight viruses and infections, which may speed up your recovery from illness (8, 9, 10).
Echinacea is frequently used to either prevent or treat the common cold because of this.
In fact, a review of 14 studies revealed that echinacea supplementation may reduce the likelihood of getting a cold by more than 50% and shorten its duration by 1.5 days (11).
Numerous research on the subject, nevertheless, have a weak design and offer little genuine value. Due to this, it can be difficult to determine if echinacea use has any beneficial effects on colds vs random events (12).
In conclusion, echinacea may increase immunity, but it is unknown how it may affect the common cold.
May lower blood sugar levels
This includes heart disease, type 2 diabetes, and a number of other chronic illnesses.
Research in test tubes suggests that echinacea plants may aid in lowering blood sugar levels.
An Echinacea purpurea extract was demonstrated in a test-tube investigation to inhibit enzymes that break down carbs. If you ate this, it would lower the quantity of sugar that entered your blood (13).
By activating the PPAR-y receptor, a popular target of diabetic medications, echinacea extracts were found to increase cells’ sensitivity to the effects of insulin in additional test-tube tests (14, 15).
A risk factor for insulin resistance, excess blood fat is eliminated by this specific receptor. As a result, cells respond to insulin and sugar more quickly (16).
Research on how echinacea affects blood sugar in humans is still inadequate.
May reduce feelings of anxiety
Nearly one in five American adults suffer from anxiety, which is a widespread problem (17).
According to research, echinacea plants contain substances that may help people feel less anxious. Alkamides, rosmarinic acid, and caffeic acid are a few of these (18).
Three out of five echinacea samples reduced anxiety in a mouse research. In addition, unlike higher doses of conventional treatments, they did not cause the mice to become less active (18).
Another study discovered that Echinacea angustifolia extract significantly decreased anxiety in rats and people (19).
However, there are currently very few studies on echinacea and anxiety. Before echinacea products are suggested as a potential treatment, more research is required.
Anti-inflammatory properties
Your body naturally promotes healing and defends itself by inducing inflammation.
Inflammation can occasionally become out of control and persist longer than intended and necessary. This could increase your risk of developing chronic illnesses and other health issues.
Echinacea chemicals reduced significant inflammatory markers and inflammation-related memory loss in a mouse research (20).
Adults with osteoarthritis who took a supplement containing echinacea extract for 30 days noticed a significant decrease in swelling, chronic pain, and inflammation.
Interestingly, echinacea extract-containing supplements were effective for these adults even though they did not respond well to traditional non-steroidal anti-inflammatory medicines (NSAIDS) (21).
May help treat skin concerns
In a test-tube experiment, researchers discovered that the anti-inflammatory and antibacterial characteristics of echinacea inhibited the growth of Propionibacterium, a common acne-causing bacteria (22).
Another study on 10 healthy adults aged 25 to 40 found that using skin care products with echinacea extract increased skin moisture and decreased wrinkles (23).
Similar to this, it has been demonstrated that a cream containing Echinacea purpurea extract can lessen eczema symptoms and aid in repairing the skin’s thin, protective outer layer (24).
Echinacea extract doesn’t seem to have a long shelf life, making it challenging to use in industrial skin care products.
