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.
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.
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.
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.
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.
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 work—at 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.
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.
The flu: Does vitamin D help?
Can taking vitamin D reduce your risk of getting the flu or a cold? The response is perhaps. However, keep in mind that the best preventative is the common sense you’ve been hearing before you start using pills:
- Always wash your hands.
- use hand sanitizer.
- To improve your resistance, get 7 to 8 hours of sleep per night.
- To prevent transferring germs to other people, sneeze into your sleeve or elbow.
- If you belong to a high risk population, get your flu immunization.
- Keep an eye out for flu symptoms and visit your doctor if you suspect you have it.
What more can you do to avoid becoming sick, though? Well, a cheap over-the-counter vitamin D supplement may aid in reducing your risk of illness by strengthening your immune system. But keep in mind that the studies are not conclusive. Taking vitamin D is not a surefire defense against the flu or the common cold. However, vitamin D pills are reasonably priced and might help.
Vitamin D: According to recent studies, those who have low amounts of vitamin D in their blood are more susceptible to illness. According to research, vitamin D may help to strengthen immunity. Don’t inquire about vitamin D-rich meals, though. Simply put, there aren’t many foods that are reliable providers of D. The sun is intended to help us produce vitamin D. But most of us don’t spend enough time outside in the sun to produce the vitamin D we require. The only thing left are vitamins.
As for the recommended daily intake of vitamin D, aim for 1000–2000 IU. This is how you obtain it:
- daily intake of 1000–2000 IU of vitamin D
- 400–800 IUs per multivitamin
- D supplements plus calcium equal 200–400 IU.
Check the amount of vitamin D in a multivitamin if you take one daily. Approximately 400 IUs each day come from your multivitamin. But if you take a women’s formula, you can be getting as many as 800 IU. Add the amount from any calcium supplements you take that also include vitamin D to your daily total. You can easily add an additional vitamin D tablet if your total falls outside of the 1000–2000 IU range. They are available in doses of 400 to 2000 IU. The little tablets are available at the majority of large grocery and drug stores, and the supplements are of high quality.
Echinacea: Is it dangerous?
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.
