A number of compounds found in echinacea contribute to its medicinal properties. Polysaccharides, glycoproteins, alkamides, volatile oils, and flavonoids are a few of them.
The chemical composition of the root is very different from that of the plant’s upper half. For instance, the plant’s above-ground portions often have more polysaccharides whereas the roots have higher quantities of volatile oils (odorous compounds) (substances known to trigger the activity of the immune system). The positive effects of echinacea are caused by the combination of these active ingredients, while research indicates that the above-ground part of Echinacea purpurea is the most efficient.
The above-ground components of Echinacea purpurea are permitted for the treatment of colds, upper respiratory tract infections, urinary tract infections, and slow-healing wounds in Germany (where herbs are subject to government regulation). It is also permitted to use the root of the Echinacea pallida plant to treat diseases that resemble the flu.
Which echinacea kind is best for colds?
Echinacea is frequently consumed in the hopes of enhancing immunity. Mixed findings have emerged from studies.
Evidence to date indicates that echinacea may marginally reduce your risk of contracting the common cold. But once you have a cold, there is currently no known way to lessen its duration. It has been suggested in some research, many of them tiny ones, that taking echinacea may shorten colds and lessen the intensity of their symptoms. Two sizable clinical trials, though, revealed no benefits at all.
Echinacea comes in a variety of species, including Echinacea purpurea, Echinacea pallida, and Echinacea angustifolia. Researchers examining various types could be the cause of some of the contradictory findings. Studies on Echinacea purpurea provide the most convincing support for the use of echinacea as a cold remedy. Studies on Echinacea angustifolia and other echinacea roots have shown less convincing findings. In comparison to older adults, echinacea may not be as effective in children and young adults.
Oral echinacea may help prevent recurring vaginal yeast infections when used with an antifungal lotion. There is conflicting data, despite some research’ claims that echinacea may modestly lessen flu symptoms.
Herpes does not appear to be prevented or treated by echinacea. It is unknown how echinacea affects other ailments.
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.
Why not take echinacea, you ask?
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.
What are the two echinacea varieties?
In addition to being widely available in garden centers and seed catalogs, echinacea faces the threat of losing its natural habitat.
One of the most recognizable herbs in use today is this grassland plant. But popularity comes with a price, and in meadows the plant was swiftly removed to supply a booming supplement industry, making it an easy target. Today, a rising number of suppliers are required to maintain echinacea in natural settings and cultivate it sustainably thanks to initiatives like United Plant Savers. Their efforts ensure that this magnificent plant is available to everyone.
Which Echinacea to Use?
Did you know that there is some debate on the best echinacea to use? You may have noticed that the echinacea in your seed catalog comes in a variety of new hues. You may have also observed that your preferred herb seller offers at least two options.
What is the difference between species?
Echinacea angustifolia and Echinacea purpurea are the two species that are most widely distributed. Both are native to different regions of the United States, but the Native Americans only used Echinacea angustifolia when we first learned about their usage of this plant. They started utilizing Echinacea purpurea instead of Echinacea angustifolia since it was so common in Europe at the time it was introduced to the supplement industry.
Echinacea purpurea is frequently thought to be less potent than Echinacea angustifolia and consequently inferior. Echinacea angustifolia is unquestionably more uncommon, and many people find it a little more challenging to grow. Which one to use is really a matter of interpretation, and there are plenty of herbalists who will support both sides of the debate with convincing proof that they are both effective. My research suggests that we may need to utilize Echinacea purpurea in higher amounts than we would need to use Echinacea angustifolia, at the very least.
Do I Use the Leaf or Root?
You may typically find echinacea’s dried leaf and dried root in herb catalogs. The plant was traditionally utilized for root preparations, but we now know that the compounds needed to strengthen our immune system are present in all plant sections. The ideal approach to make an echinacea tincture is to start with a leaf tincture early in the season, add flower in the summer, and finish with a little root in the fall.
How Is Echinacea Used?
The benefits of both echinacea species are greatest when the body is infected. The entire plant is highly beneficial for conditions including a sore throat with pus-filled areas, which is comparable to strep throat. Conditions involving advanced infection or tissue deterioration benefit greatly from echinacea. It can be applied in situations where the system has been overworked and stressed out in general. The substances in this plant direct our white blood cells to migrate quickly to an area where our body is struggling to fight an illness. This is the reason I don’t suggest using echinacea as an immune system tonic or preventive.
Where to Get Echinacea
If you choose to use echinacea into your teas or tinctures in order to prepare for the winter’s illnesses. Make sure to purchase them from a dependable herb supplier that is protecting native populations, such as Mountain Rose Herbs. You can be confident that, regardless of the species you pick and the plant part you want to use, you will benefit in the event of an illness.

Flower:
A single flower with 15 to 20 pink to light purple rays (petals) that are each 3/4 to 11/2 inches long and 1/4 to 1/3 inch diameter and have three notched teeth at the tip can be found at the end of a sturdy, hairy stalk. As they mature, rays sag and curve under as they spread out and rise. Large round to conical orangish brown disk in the middle is covered in tiny brown disk flowers that have yellow pollen. Usually, a plant has one to several flowering stalks.
Leaves and stem:
The majority of the leaves are basal, while the bottom part of the stem has stem leaves that are widely spread and alternately attached. Lower leaves have long, narrow, up to 8-inch stalks that are 1/2 to 1 inch wide, and as they climb the stem, they get shorter and lose their stalks. There are three distinct veins along the length, and the edges are toothless. The stems and leaves have rough, hairy surfaces. Stems may have purple or green undertones.
Notes:
Although it is not a common species in the nursery industry, narrow-leaved purple coneflower is a native of western sandy grassland and is frequently offered by native seed dealers. This plant has similar leaves to Echinaceae pallida (Pale Purple Coneflower), but its ray petals are only about 1/8 inch diameter and up to 3 inches long. According to some references, this plant is a western variant of that plant. Eastern Purple Coneflower (E. purpurea) contains similar flowers to E. angustifolia, but its lanceolate leaves are shorter, broader, and extend all the way up the stem. Only one of these three native coneflowers, E. angustifolia, is indigenous to Minnesota, but the other two thrive here and are frequently sold at native plant markets. The wildflower trade also carries E. tennesseensis, an eastern variety from the central Tennessee forest glades.
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.
Is zinc echinacea effective?
Physical barriers, innate immunity, and adaptive immunity are among the immune-system defenses frequently used to combat the common cold, according to a review of 82 studies. Vitamin, vitamin D, zinc, and echinacea can further support these defenses.
Further evidence for the efficacy of those minerals to enhance immune system maintenance and lessen the severity and duration of cold symptoms comes from a new review1 of 82 previously published studies on echinacea (Echinacea purpurea), zinc, and vitamins C and D. The review, which was published in the journal Evidence-Based Complementary and Alternative Medicine, discovered that echinacea, vitamin C, vitamin D, and zinc can all support the immune system’s physical, innate, and adaptive defenses against the common cold. The analysis also offers guidance on the appropriate timing and length of taking supplements of vitamin C, vitamin D, zinc, and echinacea to lessen cold symptoms.
The length and intensity of a cold episode are both reduced by keeping a robust immune defense system, according to the study’s authors. In this analysis, the researchers specifically aimed to evaluate the effects of vitamin C and D supplementation, zinc, and echinacea on the physical barriers, innate immunity, and adaptive immunity, three major immune-health interacting clusters. They noted that physical obstacles include mucus secretion, the acidity of the stomach, a low pH brought on by certain fatty acids and enzymes, which can restrict bacterial development. Immune system components such NK cells, cytokines, macrophages, and neutrophil granulocytes are referred to as innate immunity. The T and B cells are a part of the third barrier, adaptive immunity, which is developed later in life, such as after a vaccination.
According to a review of the available data, consistent vitamin C supplementation (1 to 2 g/day) cuts the length and intensity of common cold symptoms by 8% in adults and by 14% in kids. However, the authors also note out that participants may be told to eat zinc within 24 hours after the onset of cold symptoms. Zinc was found to reduce the duration of colds by about 33 percent. In the meantime, vitamin D offered defense against the common cold. Patients in the studies examined in the current analysis who were vitamin D deficient benefited most from vitamin D supplementation in terms of their immune systems. Over the course of four months, subjects who supplemented with echinacea (2400 mg/day for prevention and 4000 mg/day during the acute stages of colds) appeared to experience fewer cold symptoms.
The authors of this review concluded that all of the nutrients present “have pivotal roles of three main immunoreactive clusters (physical barriers, innate, and adaptive immunity) in terms of prevention and treatment (shortening the duration and/or lessening the severity of symptoms) of common colds.” They came to the conclusion that the current review sufficiently showed how vitamins C, D, zinc, and echinacea can be used to reduce cold symptoms and strengthen the immune system.
