Product Questions

As a Practitioner, can I include product claims on my Prescription labels?

Under the Dietary Supplement Health Education Act of 1994 (DSHEA) dietary supplements must not contain any information in the labeling or marketing of the product that makes health claims. Mayway complies to DSHEA regulations so you will notice that our website, labels and marketing materials do not have any health claims. We ask our practitioners who use the Mayway dispensary service to refrain from putting any information on the label that would be construed as a claim. Information on DSHEA regulations can be found at the FDA Website.

Examples of prescription label claims:

  • For lung infection. Take 3 times before meals.
  • Yeast infection formula
  • Ann's Headache Formula


If an herb has a higher grade (example: Shan Yao#1), does that mean it is of a higher quality, or just a different size or cut?

Higher grades are almost always a larger cut coming from a more mature plant. This usually means that the cut is also of better quality.

Why do some herbs look radically different from what I have been getting in the past from Mayway and/or other suppliers?

Although in some cases it may be due to proprietary Plum Flower® cutting and processing methods (see question below), most likely it is due to the herb being of a different species. We believe it is important for us to promote the use of the correct species of herbs as specified in the People's Republic of China's Herbal Materia Medica, as these are the herbs practitioners are taught to prescribe. In the U.S., many southern species have been substituted due to the large number of southern Chinese doctors, teachers, and importers of Chinese herbs. Although in many cases the actions and indications of the substitutes are the same, or very similar, in some cases they are only superficially alike, and thus potentially ineffective or even harmful. Please feel free to check with us whenever you are unsure.

Why are some Plum Flower® Premier Quality Herbs drier than other brands?

Plum Flower® Premier Quality Herbs are processed using proprietary methods that allow us to avoid the prevalent use of sulfur dioxide fumigation, a preservative also used to artificially “enhance” the appearance of herbs. One of these proprietary methods involves special cutting and drying techniques. When these specialized techniques are combined with our meticulous vacuum packing and nitrogen injection process, they allow us to provide high quality, clean herbs without sulfur dioxide treatment or other preservatives. More details about how Plum Flower ® Premier Quality Herbs are processed can be found in this article, Herb Processing at the Mayway Hebei Facility.
