A genus of flowering plants in the daisy family are referred to as echinacea. They naturally grow in prairies and open, forested places in North America. Only three of the nine species that make up this group—Echinacea purpurea, Echinacea angustifolia, and Echinacea pallida—are used as herbal supplements ( 1 ).
What components make up echinacea?
Alkamides, polysaccharides, and derivatives of caffeic acid (phenolic compounds) are the principal active ingredients in echinacea. Several components, including caftaric acid, chlorogenic acid, caffeic acid, echinacoside, and cichoric acid, are recognized as caffeic acid derivatives from echinacea extracts.
What is the health benefit of echinacea?
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.
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.
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.
Where is the origin of echinacea?
Echinacea is a common ingredient in over-the-counter medications available in pharmacies and health and nutrition stores. It is widely believed to prevent and treat colds and the flu.
A genus of flowering plants in the daisy family is called echinacea. Its nine wild species thrive in open forested areas and damp to dry plains in eastern and central North America.
The genus include the narrow-leaved purple coneflower, pale purple coneflower, and purple coneflower. They all open their huge pink petals in the early to late summer.
More house owners are including different types of the coneflower in their gardens as a result of its acceptance as a herbal supplement. According to the National Garden Bureau, echinacea has consistently ranked in the “top five” perennials for retail sales.
According to a garden bureau document, “Echinacea was picked as the plant of the year for 2014 because it’s such an American mainstay.”
However, the joy may not last long for at least one species of wild coneflower, the narrow-leaved purple coneflower (Echinacea angustifolia).
According to Ruth Shaw, an evolutionary scientist at the University of Minnesota, the narrow-leaved purple coneflower, a native of the tallgrass prairie and North American Great Plains, “was previously plentiful and had a vast distribution.”
“But many plains were turned into agricultural areas after European settlers began to arrive around 1870. Coneflowers and other prairie wildflowers were trampled under.
According to research by Shaw and his colleague Stuart Wagenius of the Chicago Botanic Garden, the coneflower is now only found in grassy areas that are still vestiges of the prairie.
The researchers are analyzing the genetic makeup of narrow-leaved purple coneflowers in a Douglas County, Minnesota grassland as part of a Long-Term Research in Environmental Biology (LTREB) grant from the National Science Foundation (NSF).
They are learning how such dispersed plant communities adjust to environmental change in the process.
These tiny patches of prairie are intruded upon by railroad tracks and row crops. According to Shaw, native prairies are teeming with vegetation and pollinators, but our 27 research locations have reduced to being little more than coneflower islands.
Many of us utilize an extract of echinacea for our health, says Sam Scheiner, program director for the NSF’s Division of Environmental Biology, which is funding the research. We can also learn more about the health of entire ecosystems by studying live echinacea plants.
According to Scheiner, “human activities have reduced wildlands and fragmented the environment, with uncertain repercussions for the local plants and animals. We can manage natural places more effectively if we comprehend how Echinacea is responding.
According to Wagenius, tallgrass prairie is one of the world’s most endangered environments. “We intend to immediately gain as much knowledge as we can about it. We might be able to save at least some of these prairie patches with some work.
When tallgrass prairie covered the Midwest more than a century ago, it provided a haven for numerous coneflowers and the bees that pollinated them. According to Wagenius, a bee might have been able to travel through a 100-mile-long field of coneflowers. “Would it be able to accomplish that now? No way.”
According to him, pollination of coneflowers in tallgrass prairies like those in Minnesota is far from optimal. Bees can only transport pollen a short distance. Bees must fly farther and farther to reach coneflowers as there are less and fewer of them in a given location. The given pollen is frequently not grade-A.
Coneflowers eventually develop a genetic bond with one another, becoming floral cousins and siblings where areas of tallgrass prairie are small enough. When a bee transports pollen between coneflowers that are related, the receiving plant could reject the pollen. After then, no new coneflowers emerge, and no new seeds are generated.
Inbreeding takes place when a plant that is genetically related accepts the pollen. The resulting weakling coneflowers frequently die.
According to Wagenius, “we’re acquiring a fresh understanding of why populations of these plants are becoming so limited through our research of coneflower genetics.
Prairie coneflowers are not just threatened by a lack of high-quality pollen. The aphids come next.
Aphids are the scourge of every home gardener, and they are just as bad for wild plants. Shaw and Wagenius found that destroying coneflower habitats can make Echinacea more vulnerable to pests.
They did research on an aphid that prefers to eat the narrow-leaved purple coneflower.
Coneflowers received bad news from the findings. The genetic “fitness” of these plants may be diminished by aphids’ predilection for inbred coneflowers, claims Shaw.
Coneflowers require more than just a large environment. They also require open fires. According to Shaw, fire is essential to the wellbeing of prairie ecosystems.
Lightning-caused fires cause grassland plants to blossom, which may increase genetic variety in the areas where the fires have burned.
However, most of the fires have been put out by roads and cornfields, according to Wagenius, and there isn’t much prairie left to burn.
The effects of fire on tallgrass prairie are the subject of scientific research, and environmental managers are urged to restore controlled fires to the prairie.
Otherwise, purple coneflowers with thin leaves and the tallgrass grasslands they represent may soon go extinct.
Echinacea and kidney health
If you have renal illness, stay away from herbal medications because they can increase blood pressure.
Some, like St. John’s Wort (for poor mood), may interfere with renal disease medications.
Before using some, such as the cold and flu treatment echinacea, consult with your doctor or pharmacist because they may have an adverse effect on kidney function.
Another issue is that the amount of the active ingredient in herbal remedies can vary significantly across brands (and even between batches of the same brand). This makes it challenging to anticipate how potent a dose will be.
Echinacea is it toxic?
Coneflowers are a lovely, low-maintenance addition to a sunny garden, and you may have even heard Echinacea used in herbal medicines, but does that indicate that it is safe for kids, animals, and other creatures to eat?
Echinacea species are not generally thought to be poisonous. A UC Davis study found that the plant’s entire composition is regarded as safe for consumption.
However, consuming enough of any new plant material could upset your stomach or digestive system, so speak to your doctor or veterinarian right away if you are worried about your child, dog, cat, or other animal.
Can echinacea be taken with vitamin D?
Vitamin D3 and echinacea did not interact in any way. This does not imply that there are no interactions, though. Always get advice from your doctor.
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.
