Learn the Truth About these Top Sellers

An estimated 18 million adults use herbs in some form, and the sale of these products continues to increase.
 
Herbal supplements, which come from plants that have medicinal properties, claim to cure, treat, or prevent disease. But when an herbal supplement is billed as “natural” on the label, that doesn’t ensure its efficacy, purity, or safety. Although there are proven health benefits for some herbal products, potentially harmful effects exist for others. 
 
Claims about herbal products are often based on folklore or testimonial instead of scientific studies. It is important to read reliable information and search out unbiased sources of research, when available. Because herbal supplements are not standardized, the same herb can be found in different products in varying amounts. This can lead to toxic levels that may cause harmful reactions in the body. Do not assume that "natural" means safe.
 
To reduce health risks when choosing and using herbal supplements:
  • Always tell your doctor if you are taking herbs. Herbs can interact with other medications causing serious side effects.
  • Do not self-treat serious medical conditions with medicinal herbs.
  • Do not take herbal supplements if you are pregnant or breastfeeding. There is no way to determine what level of herbs may harm a fetus or nursing infant.
  • Do not give herbal products to children under 3 years of age. Always check with your child’s pediatrician first.
  • Only purchase herbal supplements that display an expiration (or use-by) date, as well as a lot or batch number.
  • The herbal supplement should state which part of the plant was used to make the product, such as root, leaf, or blossom.
  • If a blend of ingredients is used in the herbal supplement, the label should list the individual ingredients as well as the amount of each.
  • Although not required, the supplement should indicate the type of solvent used when processing the herb.
Check for certification symbols, such as:
  • A United States Pharmacopeia (USP) symbol verifies that the product contains the stated ingredients in amounts and strength, is pure, meets limits for contaminants, and disintegrates quickly.   
  • NSF International verifies products for content and label accuracy, purity, contaminants, and manufacturing processes.
  • ConsumerLab.com independently tests supplements for purity and active ingredients. A supplement company can pay to have its product evaluated, use the seal of approval, and be listed on the website.
Be a smart shopper! Use the following resources to research beyond the product information provided in stores:

  • I think herbal supplements can be great but, working in a pharmacy, I wish people would ask the pharmacist or staff about them. Some react very badly with prescription medications. Example? Garlic reacts with oral birth control in such a way as to render the birth control completely useless. - 7/31/2014 4:09:42 AM

    These supplements should be outlawed, how much money do the rip off companies that sell them have to make from people believing all the nonsense?? In 2014, no adult should be believing the advertisements of these products, 70% of them don't even have the stuff in them that the bottle says on the label, for heaven's sakes. Praise be to BRAINS, people! - 7/17/2014 2:09:04 PM

    I wanted to thank you for this wonderful program. After years of trying to conceive and a failed IVF and a failed FET, I ordered your Pregnancy Miracle Herb @ lifecentre@live.c
    om. According to my infertility doctor it was "very unlikely" that I could be pregnant with my own eggs. But here I am, pregnant for the first time in life. I got pregnant naturally just 2 months after my failed FET and after following your plan. I am now 7 month pregnant . I am spreading this miracle story to whomever I meet and who suffers from infertility. Kind regards and thank you, Priest Hallifat!"

  • Kava kava has been used safely throughout most of the Pacific for hundreds, if not thousands, of years. It produces a mild relaxation in the body without affecting mental function. The amount of kava kava in a standard herbal capsule is ridiculously small--there is absolutely no way this can cause liver damage unless you are consuming a full bottle of herbs every single day for an extended period of time. Kava, kawa, awa, yanquona, whatever it is called on whatever island, it is completely safe unless taken to ridiculous excess. I would highly recommend kava kava over muscle relaxants, Valium, Xanax or any of the other chemicals manufactured by Big Pharma. - 9/11/2012 8:28:16 PM
  • Feverfew pills gave me major mouth sores. I didn't realize that they are part of the mum family that I'm very allergic to. What a headache.
    St.John's Wort put me into Seritonin overload resulting in Seritonin Syndrome. Boy that was depressing.
    I take Melatonin for sleep, but not every night because it gives me the weirdest dreams if I do.
    If you have allergies or food sensitivities, my advice would be to take care and don't start a regular routine without professional monitoring. And definitely don't take a supplement if you don't know the brand or where it was made. This market is not controlled enough for quality and double blind testing. I don't think hearsay is enough. There are lots of good brands out there who stand behind what's in their product.
    Think about the bogus drugs shipped from China and other places. The herbal remedy market is big bucks too and is just a susceptible to people out to make a buck for nothingl - 9/11/2012 1:01:40 PM

    I'm all for herbs. All this hoopla over side affects and such is a lot of bull. You get the same, if not worse, with prescribed medicines. - 9/11/2012 10:32:33 AM

    Since I have mood and anxiety problems, I am taking several supplements (Vitamin B complex, 5-HTP, GABA, Passion flower extracts, and a mixture of vitamins/minerals for women) - I feel good with this but feel the need to let you out there know that I was running into issues with my birth control while taking St. John's Wort: I can lower the effectiveness of it.
    I switched to 5-HTP to keep my mood more stable. - 9/11/2012 10:13:09 AM
  • Sounds like BIG Pharma wrote this. I work for Healthy Directions and its sounds like propaganda. - 9/11/2012 10:09:37 AM

    St. Johns Wort interferes with a major metabolic pathway in the liver through which many medicines pass. It can therefore interfere with estrogen, reducing contraceptive and HRT effectiveness, also it can reduce the effectiveness of treatments for epilepsy and pain relief amongst others.
    It is best completely avoided if you are taking any prescribed medication or if you may be pregnant.
    If anyone believes they may be suffering from depression it is important that a proper diagnosis is obtained before starting any treatment. - 6/6/2012 12:52:45 PM
  • Cranberry supplements DO work to keep UTIS away! Don't take a lot of other things, sure they are safe but have a good immune system and seldom get sick so I don't feel I need any of them... - 3/30/2012 1:06:12 AM
  • MIKI....i would be very interested in some of the supplements you take specifically for breast cancer. I was diagnosed in 2010 (2 yrs this month) and mine was also encapsulated, took chemo and radiation, and had a nervous breakdown! I still struggle with my faith and nerves almost daily! I am currently trying to lose weight as cancer is linked to obesity (have lost 21 lbs) and have started taking supplements i feel may help support my diagnosis but i am only guessing. I am taking a vitamin and fish oil and vitamin D3 and calcium and flaxseed oil along with 2 prescription drugs for other ailments. I have also been drinking loose leaf tea. If you are willing to share I would love to hear what you have learned. If not...I understand....Tha
    nk you in advance.....Nadin

  • I got breast cancer the first time in 1987. It was encapsulated, so removed and went on with life. Six years later(supposedly "safe") I got breast cancer again on the other side. It was late stage 2 and growing fast since I found it within 2 weeks. My surgeon told me it was not the same cancer returning, just that I was "prone to cancer." I did chemo and radiation and after I finished, a year later, I met the woman who became my herb teacher and started taking classes and doing herbs. It has been nearly 20 years and I not only have not had cancer again, I don't get ill. Once in awhile I can tell my body is fighting something off so I feel icky, but after a day or so, I am good to go. For someone "prone to cancer", not too bad!!
    I will never give up my herbs!
    Oh yeah, I spoke to a guy who had had an inoperable brain tumor. His doctors told him to go home and put his affairs in order. His wife dragged him to my teacher, who put him on a strict regimen of herbs and diet. Five months later, the cancer had shrunk to the size of a thumbnail and the docs said they could operate. He said he'd stick to what was working.A month after that the tumor had also shrunk and a month after that everything was gone. Pretty great, huh?! - 2/7/2012 3:44:31 PM
  • I respectfully disagree with this article. Herbs have been used (tested) for thousands of years by the world's indigenous people. The resistance to herbal supplementation in the USA is more due to propaganda from Big Pharma than anything else. Just as you would not walk into a pharmacy and pick your own drugs, so it is with herbs. Herbal remedies are effective and safe when recommended by a practitioner who knows what he/she is doing. The risks of side effects of drugs that treat symptoms instead of causes grows longer everyday. Western medicine is great for putting you back together after a car crash but so many diseases can be prevented and cured by smart nutrition and natural supplementation. - 2/7/2012 3:37:58 PM
  • Yea Valerian! I am a huge fan of Valerian for helping quiet my mind and getting to sleep without a drowsy feeling the next morning. It smells like dirty gym socks so I lean toward the standardized capsules from Whole Foods. - 2/7/2012 12:17:45 PM
  • I am amused and irritated by the vast amount of energy used in warning mankind about the risks of herbals. Where o where, learned sparkpeople scholars, are the warnings about chemically altered, genetically engineered, and/or otherwise modified foods? I guess it has to do with the government insisting that these are all safe as can be but those naturally derived herbals... wow... gotta be scairt of those! - 2/7/2012 8:51:19 AM
