Introduction to Chinese Herbs

Chinese herbal medicine has a profound history that forms the backbone of an outcome-driven healthcare system. Spanning from the early Han Dynasty to the late Han Dynasty, this ancient practice witnessed significant advancements, refinement, and expansion. During this period, clinical experience led to the refinement of medical theories, pulse diagnosis, acupuncture techniques, and herbal prescriptions. Classical texts emerged, providing a systematic framework for Chinese medicine and guiding practitioners for generations to come.

One of the most influential texts, the Huangdi Neijing (Yellow Emperor’s Inner Canon), compiled around the 2nd century BCE, synthesized medical knowledge and theories of the time. Divided into the Suwen (Plain Questions) and the Lingshu (Spiritual Pivot), this treatise covered human physiology, diagnosis, treatment principles, and acupuncture techniques comprehensively.

Daoist philosophy played a significant role in shaping Chinese medicine during the Daoist Hundred Schools of Thought era. The harmony of Yin and Yang, the flow of vital energy, and the interconnectedness of humans with nature became foundational principles in Chinese medical theory. Daoist scholars and alchemists explored various substances, including herbs, minerals, and other natural materials, seeking longevity and immortality. This exploration led to the discovery and utilization of numerous herbs that are now essential components of Chinese herbal medicine.

Classical texts such as the Shanghan Lun (Treatise on Cold Damage Disorders) and Shennong Bencao Jing (Divine Farmer’s Materia Medica) further contributed to the advancement and codification of Chinese medicine. The Shanghan Lun focused on the diagnosis and treatment of complex diseases, prescribing formulas and considering acupuncture points for specific conditions. The Shennong Bencao Jing cataloged a wide range of herbs and their therapeutic properties, serving as a fundamental reference for herbal medicine.

Modern Chinese herbal medicine draws upon this rich tradition. With over 500 medical materials and thousands of formulas dating back thousands of years, practitioners combine single herbs to create multi-herb formulas for mass production or custom prescriptions. This pharmacological system requires in-depth knowledge of single herbs and the ability to create formulas that direct the chief agents to specific areas of the body. While mainstream pharmacology tends to isolate and synthesize specific chemical constituents for patenting, traditional Chinese herbs continue to provide inspiration for pharmaceutical development.

It’s worth noting that traditional medicine, including herbal medicines, acupuncture, and other local therapies, is widely used worldwide. According to the World Health Organization Global Centre for Traditional Medicine, approximately 88% of countries incorporate traditional medicine into their healthcare systems. While the US healthcare system primarily relies on synthetic medications, the medical properties of herbs have still contributed to the development of various drugs through the isolation and synthesis of specific chemical constituents.

Blending modern pharmacological underpinnings with medicinal herbs, Chinese Medical Herbology & Pharmacology provides single herb information while Chinese Herbal Formulas and Applications provides information to a range of healthcare practitioners. These texts include herb monographs; photographs, chemical structure diagrams, toxicology, cautions and contraindications, herb-drug interactions, formulas, and evidence-based research.

Chinese Herbs & Allergens: Labeling with Caution

By Shellie Rosen, DOM, Lac – Published February 2018, Acupuncture Today

[Read Full Article]

The growing prevalence and awareness of allergen-related side effects from consumable goods begs the question, “Are we labeling potential allergens appropriately?” The Food and Drug Administration (FDA) has required allergen labeling for over a decade. The ingredients the FDA focuses upon are responsible for “90 percent of all food allergies.”1 Chinese herb formulas may contain potential allergens not typically recognizable to consumers and not currently required by the FDA. Practitioners can provide an excellent service to patients by understanding the food allergen labeling law, the ingredients necessary to label, and additional Chinese herbs that are worth discussing (and labeling) with sensitive patients.

The Allergen Labeling Law

The Food Allergen Labeling and Consumer Protection Act (FALCPA) became law in 2004 (Title II of Public Law 108-282). The purpose of FALCPA was to set requirements for supplements or foods that contain a major food allergen, or proteins associated with allergens, to be appropriately labeled for consumers.

Section 403 of the Federal Food, Drug and Cosmetic Act from 1938 requires that food “fabricated from two or more ingredients declare each ingredient by its common or usual name.” FALCPA was needed to assist consumers of food and supplement products further because allergens became both more prevalent and widely known as causes of illness. Consumers required help identifying potential antagonists. Some labels under section 403 were initially not clear enough for those suffering from allergen sensitivities.

What are the Major 8 Allergens?

  • Milk
  • Egg
  • Fish
  • Crustacean shellfish
  • Tree Nuts
  • Wheat
  • Peanuts
  • Soybeans (or processed with soy)

Chinese medicine practitioners must ensure their prescriptions carry allergen labels for the ‘major eight’ allergens. The agency released a “Final Guidance” October 5, 2005 that breaks down specific areas required for labeling allergens. For example, if a product contains tree nuts or fish, the particular type of nut and fish/shellfish must be labeled. The deadline for dietary supplements to comply with allergen labeling requirements was January 1, 2006. Chinese Herb practitioners serve patients best when they contract with companies that label allergens in compliance with federal regulations.

What You Should Label

Label any ingredient that derives from a potential allergen, since labeling products is a public safety concern, especially in the case of potential allergens. FALCPA wants consumers to have access to clear language that avoids ambiguity. Labels are not compliant when they do not state the source product of the allergen. Listing “whey” isn’t adequate; the label must also say “milk.”

A product that derives from a potential allergen must label that allergen source. Perhaps there is a belief that a particular processing method may mitigate the potential threat of an allergic response. In this case, opinions shall not interfere with patient rights. For example, some individuals may be allergic to shrimp, but tolerate glucosamine made from shrimp. Perhaps because glucosamine derives from shrimp shells, not shrimp flesh where the protein that initiates an allergic response resides.

Although allergic reactions have not been problematic with shell-derived glucosamine, it is sourced from shellfish and must label as such.

Patient’s and their doctors have the right to know what products are in their prescription. If you have done research on a particular processing method and you believe potential antagonists transform enough to render the allergen source inactive, then offer your patient the information and allow them to decide with their doctor if the risk is worth it. The Chinese herbal compendium offers creative ways around potential allergens, why take a chance?
