The choices available in the health food or grocery store are overwhelming. Here are some general guidelines to help you choose a quality product.
This will take some legwork on your part, but may be helpful in determining if a company has enough internal quality control to be confident that outside, independent testing will verify the information they have put on the label. This industry is still evolving and hopefully will move toward defining, implementing, and enforcing standards so that consumers don't have to be in the position of "Buyer, beware," as is the unfortunate current situation. when I have called a couple of herb companies, all were willing to tell me if they belonged to the NNFA or not. All wanted to know why I was asking. If you call the companies yourself, simply say that as a consumer, you would like some indicator of quality control of the products you are choosing to buy. Conveying this information to the manufacturers will hopefully give them the message that higher and more consistent standards for the herbal industry are needed.
Some additional advice I give my clients is the importance of keeping a diary or log of all the supplements they are consuming, including brand name, dosage, frequency, along with recording any signs, symptoms, or changes they might notice that should be brought to the attention of their cancer team members. In addition, if you are starting a new complementary therapy such as acupuncture, meditation, yoga, guided imagery, etc., keep records of when you started that, too, along with any changes you observe. All of this information should be incorporated into your medical records because all of these strategies are contributing to your healing.
It is also advisable to introduce or change only one new herb, supplement, or therapy at a time. I recommend waiting 3-4 days at a minimum. That way the development of any adverse effects can be more easily traced to a particular change or addition, just like with a medication. currently there is VERY LITTLE information available to guide practitioners regarding potential unsafe combinations of medications and herbs. If you do develop any unusual side effects or symptoms, stop your supplements and notify your physician(s) and any additional health care practitioner who is guiding you on choices of complementary therapies.
