It is widely believed that echinacea tea can both prevent and treat the common cold. Evidence suggests that echinacea may strengthen the immune system, aiding the body’s defense against viruses and illnesses ( 33 ).
What conditions does echinacea treat?
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.
Boosts Immunity
Echinacea tea has been a go-to remedy for boosting the immune system and preventing infections for a very long time. Antibacterial qualities of echinacea help keep infections from getting you sick. Additionally, echinacea tea might lessen the aches and pains brought on by the common cold and flu and soothe a sore throat.
The influence of echinacea on the immune system was the subject of a meta-analysis published in The Lancet Infectious Diseases Journal. Echinacea reduced the incidence of the common cold by 58 percent, according to 14 trials examined by researchers. Additionally, taking echinacea reduced recovery time by 1.5 days. Even if you do contract a cold, drinking echinacea tea can help you stay healthy and recover more quickly.
Additionally, echinacea tea aids in the eradication of free radicals, which result in oxidative stress and cell damage. By delaying the beginning of early aging and brain degeneration, this contributes to an improvement in general health.
Prevents Infection
Yeast infections and urinary tract infections can be treated with echinacea’s antibacterial properties. The majority of study demonstrates that the chemicals in echinacea leaves are responsible for these health advantages. Caffeic acid and other polyphenols found in tea, in particular, exhibit antiviral properties that shield against infection.
Echinacea may increase white blood cell counts, according to certain studies, albeit these studies are still in progress. The polysaccharides in echinacea tea may be useful in the treatment of illnesses like HIV, according to several research, one of which was published in the American Journal of Clinical Nutrition. These chemical substances function by limiting the replication of damaged cells, which delays the spread of infections.
Relieves Pain
Echinacea was first utilized as a pain reliever by Native Americans. The herb is now used to cure a variety of pains, including rheumatoid arthritis and toothaches. Tea made from echinacea can be used to relieve gastrointestinal discomfort, such as cramps and irritable bowel syndrome.
Echinacea’s impact on pain was investigated in a randomized, double-blind trial that was published in Evidence-Based Complementary and Alternative Medicine. Researchers discovered that those who took echinacea used less pain medication to manage cold symptoms.
Improves Mood
Echinacea’s fragrant aroma can aid in reducing stress and depressive emotions. Dopamine, a hormone known for regulating happiness, is released in response to the aroma of echinacea. Cortisol, also referred to as the stress hormone, may also be reduced by echinacea.
The effects of echinacea on anxiety were explored in a study that was published in Phytotherapy Research. Echinacea dramatically reduced the excitatory synapses, according to research. This indicates that people who took echinacea extract had less dread and anxiety. Echinacea was found to modulate synapses, but it did not completely stop transmissions.
Soothes Respiratory Ailments
Upper respiratory tract infections and the symptoms of asthma may be treated with echinacea tea. These illnesses are frequently brought on by allergies or the common cold. Echinacea tea facilitates better airflow in the lungs and throat by soothing irritated muscles. Additionally, histamine, which is produced when the body overreacts to common stimuli and causes allergic reactions, is suppressed by echinacea. Echinacea has been shown to have bronchodilator and anti-inflammatory properties, according to research studies from 2015. These characteristics are comparable to those of synthetic medications used to treat asthma.
What is the most important information I should know about Echinacea?
If you have any of the following conditions, you shouldn’t use this product:
an autoimmune disease like lupus, psoriasis, or rheumatoid arthritis.
If you have any allergies, particularly plant allergies, see a doctor, pharmacist, or other healthcare professional to determine whether it is safe for you to use this product (especially ragweed, mums, marigolds, or daisies).
Never give a child any herbal or nutritional supplement without consulting a doctor. Children under the age of 12 should not take echinacea.
How frequently should echinacea tea be consumed?
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.
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).
Research has shown that echinacea plants contain chemicals that may alleviate emotions of anxiety. 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.
Will echinacea strengthen my immune system?
Echinacea may boost your immune system, enabling you to combat viral or bacterial colds and flu. According to certain studies, the echinacea plant includes compounds that aid in the production of white blood cells by your body. These white blood cells function as part of your immune system to combat infection when your upper respiratory tract (nose, mouth, and throat) becomes infected.
But a 2014 research that examined two dozen additional studies discovered only flimsy proof that echinacea supplements actually work to treat colds. Echinacea may help treat colds, but it has not been demonstrated to hasten the onset of a cold.
Several different infections may be repelled by echinacea. According to some research, echinacea helps treat ear infections, urinary tract infections, and slow-healing cuts and wounds. Even though echinacea can occasionally assist with small illnesses, if the issue persists, you should visit a doctor.
Are bacterial illnesses treated well by echinacea?
The herb echinacea is indigenous to parts of the United States east of the Rocky Mountains. In addition to Canada and Europe, it is also grown in the western United States. The leaves, flowers, and roots of several echinacea plant species are used to create medication. The Great Plains Indian tribes utilized echinacea in their traditional herbal treatments. Later, settlers copied the Indians and started utilizing echinacea as a medicine as well. Echinacea had official status for a while because it was included in the US National Formulary from 1916 to 1950. However, the development of antibiotics caused echinacea use to decline in popularity in the United States. But now that some antibiotics are less effective than they formerly were against specific germs, echinacea is regaining popularity.
The common cold, the flu, and other upper respiratory illnesses are among the ailments for which echinacea is frequently used as a treatment. Some people hope to prevent a cold from developing by taking echinacea as soon as symptoms appear. Some individuals use echinacea after the onset of cold symptoms in an effort to lessen the severity of the illness.
Echinacea is also used to treat a variety of other illnesses, such as warts, ear infections, swine flu, ear infections, vaginal yeast infections, HIV/AIDS, herpes, tonsillitis, streptococcus infections, HIV/AIDS, syphilis, typhoid, malaria, and bloodstream infections (septicemia).
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.
