Frequently Asked Questions

Q. Why should I use herbal products?

Herbs and herbal products provide real health benefits while maintaining a remarkable safety profile. In fact, the World Health Organization has estimated that 80% of the world's population continues to use traditional therapies, a major part of which are derived from plants, as their primary health care tools. These products are found in the form of teas, tablets, capsules, liquid extracts, and others. We now have ready access to products that bring the herbal traditions from all over the world in a variety of convenient forms.

Q. Are herbal supplement products safe?

Federal law requires that every food product, including herbal supplements, is free of "adulteration" and is not "misbranded." This legal language translates into a requirement that all foods and supplements have a reasonable expectation of safety when offered for sale and when used as directed.

There are so few credible reports of unexpected side effects due to herbal products that most experts consider problems with herbal products to be of only minor concern. Norman Farnsworth, Director of the WHO Collaborating Centre for Traditional Medicine, is generally considered to be one of the most respected experts on the scientific research of botanical medicines. In a 1993 article written on the subject of herbal safety, Dr. Farnsworth concluded, "...side effects or toxic reactions associated with herbal medicines in any form are rare. In fact, of all classes of substances reported to cause toxicities of sufficient magnitude to be reported in the United States, plants are the least "

Responsible and informed use by consumers is essential to insure that herbal products maintain their established safety profile. Accurate product labeling must provide

Q. What is nutraceuticals?

Combining the terms for nutrition and pharmaceutical, the term "nutraceuticals" refers to foods or supplements that provide health and medical benefits.

Q. Should I tell my Doctor that I'm using herbs?

Of course! And because your doctor is, ideally, your primary partner in managing your health, you should insist that your doctor receive that information respectfully. In telling your doctor of your decision to use an herbal product; however, don't be surprised to find that your knowledge of herbs is more advanced.

Q. What about interactions with prescription drugs?

The introduction of synthetic and highly purified drugs is an extremely modern development. As researchers observe the interactions that drugs have with common foods and herbs, surprises continue to surface. For example, about 10 years ago it was found that drinking grapefruit juice increases the serum drug concentration when patients take certain drugs. This effect, which can last for up to hours after consumption, is now thought to inhibit specific enzymatic activities responsible for breaking down the drugs. Similarly, both avocado and leafy vegetables that are high in vitamin K can diminish the effectiveness of blood-thinning drugs. These concerns are not widely known by the public, but we at Chi’s Enterprise are aware of such reactions and routinely monitor our products to assure safe and effective results. However, clients with specific medical concerns should consult their private physician before consuming both herbal supplements and prescribed medications.

Q. How effective are Chinese herbs?

Chinese medicinal herbs have been used for thousands of years, much the same as the Europeans relied on Western herbal medicines before modern medicine was born from it. Medicinal herbs have been an important source of natural product drugs and the root of modern pharmacology.

Q. How safe are CHI supplements?

The products undergo heavy metal analysis and microbiological tests to check for contamination. When they arrive in the United States, the FDA randomly samples products and conducts further contamination tests.

Q. Are the herbs grown in China?

Yes, 80% of the herbs are grown in China, the others are obtained here in the United States. Because of specific climate and altitude requirements to grow certain herbs, some species of herbs cannot be grown in the United States.

Q. I’ve read that some patent Chinese medicinal herbs are supplemented with pharmaceuticals. How about CHI Supplements?

We believe that Chinese medicinal herbs and pharmaceuticals are not to be combined. CHI Supplements do not contain pharmaceuticals.

Q. Are CHI supplements 100% natural?

Yes, they are 100% natural. CHI supplements do not contain sugar, pharmaceuticals, artificial color, gluten or preservatives.

Q. How are CHI supplements different from other herbal supplements?

Some herbal supplements are produced by simply grinding the single herbs into powder. No extraction procedure is employed to separate the active ingredients from the inactive ingredients, which may compromise the efficacy of the herbs. CHI supplements are produced by identifying, extracting and purifying the biologically active fractions of the herbs to obtain the most potent ingredients.

Q. Are CHI supplements manufactured in GMP facilities?

Yes. All products listed are manufactured in Good Manufacturing Practice (GMP) certified facilities. GMP certification of a manufacturing plant is an excellent marker of quality. 

Q. Can you comment on the side effects of Chinese herbs?

Like any medicine as a whole, some Chinese herbs may have undesired side effects. However, available statistics in China show that many more adverse drug reactions are reported for chemical drugs than Chinese herbs. CHI supplements are safe and well-tolerated.

Q: Do I need to take CHI supplements separately, or can I take/mix them together?

Dietary supplements serving the same medical conditions or targeting similar bodily deficiencies can be taken or mixed together. For instance, Vein Lite and Asparagus Extract in the herbal tea form can be mixed together because both products act as detoxifying agents in the removal of acidic wastes within the body. However, many prefer the simplicity of taking one dietary supplement at a time. Products taken together or separately all result in the same level of effectiveness.

Q. How long do I need to take the herbs?

Many herbal formulas or extracts act to adjust or restore the normal physiological conditions of the body. This is not easily achievable in a few days. Depending on the indications, the herbal supplements must often be taken for an extended period of time before their full benefit is experienced.
