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 pollen delivered is generally less than 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.
Which area of the echinacea plant is therapeutic?
There are 11 plants in the Echinacea genus, the majority of which are regarded as coneflowers. These include the narrow-leaf coneflower, Echinacea angustifolia, and the sanguine purple coneflower, Echinacea sanguinea, which served as the foundation for early medicinal studies on the genus (TWC Staff, 2013, Brinker, 2013). Asteraceae is the family of plants that includes Echinacea purpurea.
Geographic Distribution and Habitat
Although E. purpurea is currently present in at least 27 states and two Canadian provinces, it originated originally from the northeast of Texas. In the eastern to central United States, E. purpurea is widespread. E. purpurea prefers sandy or loamy soil that is well drained.
Description
A perennial, E. purpurea with drooping rays that range in color from lavender to pink and a brownish central disk that contains numerous spiny seeds. The Greek word echinos, which means hedgehog in allusion to the bristly seed tops, served as the inspiration for the genus name Echinacea. Flowers can be found on a single stem, and the plant has smooth stems that are 2 to 5 feet tall. From April until September, the flowers are in bloom. The lancolate, ovate, green leaves have a rough texture and serrated or dentate margins.
Portion of the Plant Used
Due to the numerous conventional and contemporary medical applications of Echinacea purpurea, numerous plant components are utilized to variable degrees. All parts of the flower—flowers, leaves, stems, and roots—are employed in medical procedures.
Traditional Uses
Numerous ailments have been treated using E. purpurea. The primary focus of this plant’s traditional usage has been its ability to reduce inflammation, which can occur anywhere or in any situation, including on the skin or as a result of an immunological response. Herbal tea made from the blossoms is supposed to strengthen the immune system. The herb has traditionally been used to treat colds, infections, wounds, ulcers, and inflammatory skin conditions (Van Wyk et.al., 2004). There may be further unusual uses for the plant, depending on where it is in the world. Echinacea purpurea is utilized as an anti-venom in India, while it is also used to treat inflammation in Italy (Ross, 1999).
Research
Echinacea angustifolia, rather than Echinacea purpurea, was used in the genus’ early medicinal use. Even in 1923, when at least ten out of 700 doctors mentioned using Echinacea to treat influenza, doctors continued to advocate its usage (Brinker, 2013). Taking significant doses of E. angustifolia (130–1750 mg), often peaking after just one day, caused individuals to have an increase in leukocyte count, according to a 1934 study at the Eclectic Medical College (Brinker, 2013). German researchers contributed to part of the fall in the use of E. angustifolia in medicine by demonstrating that the extract only mildly inhibited gram-positive bacteria like Streptococcal and Staphylococcus aureus (Brinker, 2013).
While E. angustifolia was the subject of the majority of early investigations on the survivability of Echinaeca species, Dr. John King’s Eclectic American Dispensary, published in 1853, highlighted E. purpurea’s potential medical applications (Brinker, 2013). Despite the roots not being allowed at the time, a German Commission authorized the use of E. purpurea liquid in 1989 as a “supportive treatment for persistent respiratory and urinary infections as well as wound healing” (Brinker, 2013).
Recent investigations have demonstrated the immunostimulatory properties of this plant (Crellin, 1990). In order to determine whether utilizing Echinacea for the common cold and associated events was effective, a significant meta-analysis of previous research was conducted in 2007. (Brinker, 2013). After this meta-analysis, significant decreases in the frequency and duration of sickness were observed (Brinker, 2013). An investigation into E. purpurea’s impact on the common cold was conducted in 2012. In this study, individuals who took Echinacea extract experienced a substantial reduction in recurrent infections compared to those who took ibuprofen (Jamal et.al, 2012; Brinker, 2013).
Side Effects, Interactions, and Contraindications
Researchers hypothesize that there may be dangers associated with using the Echinacea herb in conjunction with a number of systemic illnesses, such as AIDS, leukemia, collagenosis, multiple sclerosis, tuberculosis, and some autoimmune diseases (Brinker, 2013). This theory is based in part on the impact E. purpurea has on the enzyme cytochrome P450 3A4, which influences how much medication, particularly macrolide antibiotics like clarithromycin and erythromycin, is absorbed (Brinker, 2013).
Echinacea has what advantages?
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.
Why should you avoid using echinacea?
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.
Where can I locate Echinacea in nature?
A coarse, rough-haired perennial herb native to damp grasslands, meadows, and open forests in the central to southeastern United States, Echinacea purpurea is also known as purple coneflower (Ohio to Michigan to Iowa south to Louisiana and Georgia).
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.
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.
