FDA recommends consumers talk to their doctor or health care professional about safe and effective treatments for their disease or condition. Under the Federal Food, Drug, and Cosmetic Act, homeopathic products are subject to the same requirements related to approval, adulteration and misbranding as other drug products.
There are currently no homeopathic products approved by FDA. Since homeopathic drug products have not been approved by FDA for any use, they may not meet modern standards for safety, effectiveness, and quality. This revised draft guidance proposes a comprehensive, risk-based enforcement approach to homeopathic products marketed without FDA approval. Many homeopathic products will likely fall outside the risk-based categories described in the revised draft guidance.

Newly emerging scientific techniques and approaches, many of which are mentioned in this book, provide the required testing platform for this.
Genomic testing and chemical fingerprinting techniques using hyphenated testing platforms are now available for definitive authentication and quality control of herbal products. They should be regulated to be used to safeguard consumers, but questions of efficacy will remain unless and until adequate amounts of scientific evidence accumulate from experimental and controlled human trials Giordano, Engebretson, and Garcia ; Evans ; Tilburt and Kaptchuk Evidence for the potential protective effects of selected herbs is generally based on experiments demonstrating a biological activity in a relevant in vitro bioassay or experiments using animal models.
In some cases, this is supported by both epidemiological studies and a limited number of intervention experiments in humans WHO In general, international research on traditional herbal medicines should be subject to the same ethical requirements as all research related to human subjects, with the information shared between different countries. This should include collaborative partnership, social value, scientific validity, fair subject selection, favorable risk-benefit ratio, independent review, informed consent, and respect for the subjects Giordano, Engebretson, and Garcia ; Tilburt and Kaptchuk However, the logistics, time, and cost of performing large, controlled human studies on the clinical effectiveness of an herb are prohibitive, especially if the focus is on health promotion.
Therefore, there is an urgent need to develop new biomarkers that more clearly relate to health and disease outcomes.
Predictor biomarkers and subtle but detectable signs of early cellular change that are mapped to the onset of specific diseases are needed. Research is needed also to meet the challenges of identifying the active compounds in the plants, and there should be research-based evidence on whether whole herbs or extracted compounds are better.
The issue of herb—herb and herb—drug interactions is also an important one that requires increased awareness and study, as polypharmacy and polyherbacy are common Canter and Ernst ; Qato et al. The use of new technologies, such as nanotechnology and novel emulsification methods, in the formulation of herbal products, will likely affect bioavailability and the efficacy of herbal components, and this also needs study.
Smart screening methods and metabolic engineering offer exciting technologies for new natural product drug discovery. Advances in rapid genetic sequencing, coupled with manipulation of biosynthetic pathways, may provide a vast resource for the future discovery of pharmaceutical agents Li and Vederas This can lead to reinvestigation of some agents that failed earlier trials and can be restudied and redesigned using new technologies to determine whether they can be modified for better efficacy and fewer side effects.
For example, maytansine isolated in the early s from the Ethiopian plant Maytenus serrata , looked promising in preclinical testing but was dropped in the early s from further study when it did not translate into efficacy in clinical trials; later, scientists isolated related compounds, ansamitocins, from a microbial source.
A derivative of maytansine, DM1, has been conjugated with a monoclonal antibody and is now in trials for prostate cancer Brower Plants, herbs, and ethnobotanicals have been used since the early days of humankind and are still used throughout the world for health promotion and treatment of disease.
Still, herbs, rather than drugs, are often used in health care. For some, herbal medicine is their preferred method of treatment. For others, herbs are used as adjunct therapy to conventional pharmaceuticals.
However, in many developing societies, traditional medicine of which herbal medicine is a core part is the only system of health care available or affordable. Regardless of the reason, those using herbal medicines should be assured that the products they are buying are safe and contain what they are supposed to, whether this is a particular herb or a particular amount of a specific herbal component.
Consumers should also be given science-based information on dosage, contraindications, and efficacy.
To achieve this, global harmonization of legislation is needed to guide the responsible production and marketing of herbal medicines. If sufficient scientific evidence of benefit is available for an herb, then such legislation should allow for this to be used appropriately to promote the use of that herb so that these benefits can be realized for the promotion of public health and the treatment of disease.
