What Is Echinecea?
Taken from Hair Boutique.com (Health and wellness tip of the week)
At this time of year colds and influenza becomes a big concern. Especially during the Holidays when people mingle in larger groups than normal. Due to the economy, changes in health coverage and other issues, more people are searching for alternative treatments for minor health concerns such as colds and flu.
Echinacea has become more popular as an option. It’s often combined with goldenseal as a herbal alternative for amping up the immune system to block cold and flu viruses from taking hold. Used By Native Americans Echinacea angustifolia was widely used for its general medicinal qualities by the Native North Americans who lived in the Midwestern states.
Native Americans learned of E. angustifolia by observing elk seeking out the plants and consuming them when sick or wounded. They identified those plants as elk root. Echinacea was one of the basic antimicrobial herbs of eclectic medicine from the mid 19th century through the early 20th century. Its use was documented for snakebite, anthrax, and for relief of discomfort. In the 1930s echinacea became popular in both Europe and America as a herbal medicine. Echinacea Is A Flowering Plant Echinacea pronounced ek-i-NAY-sha is a genus of herbaceous flowering plant in the Asteraceae daisy family. It’s a popular alternative herbal style of treatment believed by many to help with cold and influenza prevention and/or treatment. The generic name Echinacea is rooted in a Greek word echinos, meaning sea urchin. It references the spiky appearance and feel of the flower heads. Echinacea plants reseed in the fall. New flowers will grow where seeds have fallen from the prior year. Echinacea still falls under the category of folk remedy. You should always consult with your primary health care provider before taking any type of herbs or alternative treatments. Species Of Echinacea It’s also known as the purple coneflower. It’s a North American plant group with nine species, three of which are commonly believed to help with cold and influenza prevention. Cold And Flu Properties
The three species valued for their cold and flu properties include: 1. Echinacea angustifolia – Narrow-leaf Coneflower
2. Echinacea pallida – Pale Purple Coneflower
3. Echinacea purpurea – Purple Coneflower, Eastern Purple Coneflower The flowering plant is generally found in eastern and central North America. It thrives in moist to dry prairies and open wooded areas. It blooms from early to late Summer and is tolerant of drought conditions. Does Echinacea Really Work? Many people swear by echinacea (or combination remedies) as their go-to herb for preventing or minimizing the impact of colds and flu attacks. Does it really work for everyone who takes it? Absolutely not.
There is not one single remedy – prescription or alternative – which works 100% for all people of all ages. There are a vast number of variables which have to be considered for any type of remedy. The same holds true for echinacea. While some users of alternative treatment swear by it, others find it doesn’t help them at all.
The truth of whether echinacea works or not, and who it works for, is generally a matter of personal experience. I personally have been taking echinacea or echinacea goldenseal formulations for close to 30 years. I believe it helps me when I am fighting off a cold or flu. But it definitely doesn’t help some of my family and friends who’ve tried it. After much research I found the liquid capusules available from Gaia Herbs work best for me. Herbal teas or herbal pills have not proven to be as effective which confirms my opinion that everyone needs to do their own research, talk to their own health care professionals and make their own decisions before taking any type of alternative treatment.
Note: We do not sell Gaia Herbs at HairBoutique.com <http://www.hairboutiquemedia.com/emailmarketer/link.php?M=13681&N=803&L=52&F=H> . I mention Gaia products because they work well for me and I have used them for many years. I am sure other brands may work just as well, but I can not recommend any which I have not personally tried. Not A One Dose Treatment Proponents of echinacea assert it is not a “one-dose” treatment. In order for echinacea to work effectively, a dose should be taken at the very first sign of cold symptoms.
Subsequent doses are called for every two to four hours after the first dose, including during the overnight sleeping period, until the cold symptoms have disappeared. The several species of echinacea differ in their precise chemical constitution, and may provide variable dosages of any active ingredients. Be sure to read the suggested dosages contained on the product labels or follow instructions from your health care provider.
Possible Side Effects? Always consult with your primary care health consultant before taking echinacea to make sure you are not at risk for any side effects. When taken by mouth, echinacea does not usually cause side effects. One of the most extensive and systematic studies to review the safety of echinacea products concluded that overall “adverse events are rare, mild and reversible” with the most common symptoms being ”gastrointestinal and skin-related.” Although rare, echinacea may cause nausea, abdominal cramps, loose bowels, itching and rash. Nausea and abdominal discomofrt are more pronounced when the product is taken on an empty stomach. Echinacea has also been linked to rare allergic reactions, including asthmatic attacks, shortness of breath, and one case of anaphylaxis.
Muscle and joint aches has been associated with echinacea, but it may have been caused by cold or flu symptoms for which the echinacea products were administered. Isolated Cases Of Rare Side Effects There are isolated case reports of very rare and idiosyncratic reactions including thrombocytopenic purpura, leucopenia, hepatitis, renal failure, and atrial fibrillation. It is not clear these reactions were specifically due to echinacea and may have been part of a larger medical issue.
Experts have expressed concerns that by stimulating immune functions, echinacea could potentially exacerbate autoimmune disease and/or decrease the effectiveness of immunosuppresive formulas, but this warning is based on theoretical considerations rather than human data. To date there have been no case reports of any interactions with echinacea. The “currently available evidence suggests echinacea is unlikely to pose serious health threats for patients combining it with conventional formulas.” As a matter of manufacturing safety, one investigation by an independent consumer testing laboratory found that five of eleven selected retail echinacea products failed quality testing.
Four of the failing products contained levels of phenols below the potency level stated on the labels. One was contaminated with lead. Ultimately only select products which are known for their manufacturing safety and guality practices.
Scientific Reviews Multiple scientific reviews, trials and meta-analyses have evaluated the published peer reviewed literature on the immunological effects of echinacea. Reviews of the medicinal effects of echinacea are often complicated by the inclusion of a wide range of mixtures. Some formulas are based solely upon echinacea while others are combinations. Also, some formulations are offered in higher potency or delivery systems than others. Some use the roots versus other parts of the plants and some are offered as extracts and expressed juice. There are also three of the nine species known to help with cold and flu conditions and may be used alone or in combination with each other herbal ingredients.
Contradictory Claims Of Echinacea Effectiveness
Evaluation of the literature within the field generally suffers from a lack of well-controlled trials, with many studies of lower quality. The results tend to be contradictory. Depending upon what studies you read, echinacea works or it has no effect. A 2007 study by the University of Connecticut combined findings from 14 previously reported trials examining echinacea. The study concluded echinacea can cut the chances of catching a cold by more than half, and shorten the duration of a cold by an average of 1.4 days. A 2003 controlled double-blind study from the University of Virginia School of Medicine and documented in the New England Journal of Medicine stated that echinacea extracts had “no clinically significant effects” on rates of infection or duration or intensity of symptoms. The effects held when the herb was taken immediately following infectious viral exposure and when taken as a prophylaxis starting a week prior to exposure. An earlier University of Maryland review based on 13 European studies concluded that echinacea, when taken at first sign of a cold, reduced cold symptoms or shortened their duration. Use Of Expressed Juice And Similar The European Medicines Agency (EMEA) assessed the body of evidence on echinacea. The EMEA approved the use of expressed juice and dried expressed juice from fresh flowering aerial parts of Echinacea purpurea for the short-term prevention and treatment of the common cold. According to their recommendations: 1. It should not be used for more than 10 days at a time
2. Children under the age of one should not take it because they have immature immune systems
3. It is generally not recommended for children between 1 and 12 years of age
4. Echinacea is not recommended for use by pregnant women and during lactation Echinacea As Immunostimulator
Echinacea is popularly believed to be an immunostimulator, stimulating the body’s non-specific immune system and warding off infections. It is also utilized as a laxative. A study commonly used to support that belief is a 2007 meta-analysis in The Lancet Infectious Diseases. The studies pooled in the meta-analysis used different types of echinacea, different parts of the plant, and various dosages. This review cannot inform recommendations on the efficacy of any particular type of echinacea, dosage, or treatment regimen.
The safety of echinacea under long-term use is also unknown. History Of Echinacea Use
Echinacea angustifolia was widely used by the early Native Americans for its general medicinal qualities. Echinacea was one of the basic antimicrobial herbs of eclectic medicine from the mid 19th century through the early 20th century. Its use was documented for snakebite, anthrax, and for relief of aches. In the 1930s echinacea became popular in both Europe and America as a herbal medicine. According to Wallace Sampson, MD, its modern day use as a treatment for the common cold began when a Swiss herbal supplement maker was ”erroneously told” echinacea was used for cold prevention by Native American tribes who lived in the area of South Dakota. Although Native Americans didn’t use echinacea to prevent the common cold, some Plains tribes did use echinacea to treat many of the symptoms which could be caused by the common cold. The Kiowa used it for coughs and sore throats, the Cheyenne for sore throats, the Pawnee for headaches, and many tribes including the Lakotah used it as relief for congestion. Active Substances Like most crude formulas from plant or animal origin, the constituent base for echinacea is complex, consisting of a wide variety of chemicals of variable effect and potency. Some chemicals may be directly antimicrobial, while others may work at stimulating or modulating different parts of the immune system. All species have chemical compounds called phenols, which are common to many other plants. Both the phenol compounds of cichoric and caftaric are present in E. purpurea. Other phenols include echinacoside, which is found in greater levels within E. angustifolia and E. pallida roots than in other species. When making herbal remedies, these phenols can serve as markers for the quantity of raw echinacea in the product. Other chemical constituents that may be important in echinacea health effects include alkylamides and polysaccharides. Summary Does echinacea work to help boost the immune system and help block cold and flu viruses from attacking? There is a lot of conflicting opinions about the value of this herb. Ultimately you need to do your own research, form your own opinions and always check with your primary care provider. Warning: Always consult your health care provider BEFORE you undertake any new type of vitamin, mineral program or herbal program of any type to make sure it does not interfere with any medical treatment you may currently be on.
