1. Understanding the Prevalence of Traditional Herbal Remedies

1.1. What is Traditional Medicine?

Traditional medicine encompasses the knowledge, skills, and practices rooted in the theories, beliefs, and experiences indigenous to different cultures, serving to maintain health and manage physical and mental illnesses. (World Health Organization). This holistic approach considers the equilibrium of mind, body, and environment, emphasizing overall well-being rather than just treating specific diseases. Traditional herbal remedies form a core component of these systems, utilizing plants for their therapeutic properties.

1.2. How Popular is Traditional Chinese Medicine (TCM)?

Traditional Chinese Medicine (TCM) is a prime example of an ancient, holistic healthcare system still relevant today. With over 3,000 years of history (Xutian, Zhang, and Louise 2009), TCM emphasizes the balance of yin and yang and the flow of energy (Qi) through meridians. Herbal medicine is central to TCM, with products like Ginkgo biloba, garlic (Allium sativum), and ginseng (Panax ginseng) being widely used globally (Li, Jiang, and Chen 2008; Xutian, Zhang, and Louise 2009).

1.3. What Percentage of People Rely on Traditional Medicine in Developing Countries?

In many developing countries, a significant portion of the population relies on traditional medicine for primary healthcare. In Africa, up to 90% of the population uses traditional medicine, while in India, the figure is around 70%. In China, traditional medicine accounts for approximately 40% of all healthcare services, with over 90% of general hospitals having traditional medicine units (WHO 2005).

1.4. Has the Use of Traditional Medicine Increased in Industrialized Nations?

Yes, industrialized countries have seen a rise in the use of traditional medicine and ethnobotanicals over the past two decades. A 2007 study in the United States found that about 38% of adults and 12% of children use some form of traditional medicine (Ernst, Schmidt, and Wider 2005; Barnes, Bloom, and Nahin 2008). Herbal therapy is the most commonly used alternative medicine, excluding prayer (Barnes, Bloom, and Nahin 2008).

1.5. Why Do People Choose Traditional Medicine Over Conventional Treatments?

Several factors drive the use of traditional medicine: affordability, alignment with personal beliefs, concerns about synthetic drug side effects, a desire for personalized care, and greater access to health information.

In 2005, China’s herbal product sales totaled US$14 billion, and Brazil’s revenue from herbal medicines was US$160 million in 2007. The estimated annual worldwide market for herbal products approached US$60 billion (Tilburt and Kaptchuk 2008).

3. Common Applications and Forms of Herbal Medicine

3.1. What Conditions Are Commonly Treated with Herbal Medicine?

Herbal medicines are used to treat chronic and acute conditions such as cardiovascular disease, prostate issues, depression, and inflammation, as well as to boost the immune system. During the 2003 SARS outbreak, traditional herbal medicines played a key role in China’s strategy to contain and treat the disease. In Africa, the Africa flower has been used for decades to treat HIV-related wasting symptoms (De Smet 2005; Tilburt and Kaptchuk 2008).

3.2. In What Forms Are Herbs and Plants Typically Available?

Herbs and plants are processed and available in various forms, including whole herbs, teas, syrups, essential oils, ointments, salves, rubs, capsules, and tablets. These products contain ground or powdered raw herbs or their dried extracts. Extraction methods vary in solvent type, temperature, and extraction time, including alcoholic extracts (tinctures), vinegars (acetic acid extracts), hot water extracts (tisanes), decoctions, and macerates.

3.3. How Do Herbal Extracts Vary?

Herbal extract components can vary significantly between batches and producers due to a lack of standardization.

4. The Role of Herbal Medicine in Modern Drug Development

4.1. How Have Plants Influenced Pharmacological Research and Drug Development?

Ethnobotanicals are crucial for pharmacological research and drug development. Plant constituents are used directly as therapeutic agents, starting materials for drug synthesis, or models for pharmacologically active compounds (Li and Vederas 2009). Morphine, the first pharmacologically active pure compound, was derived from opium extracted from poppy seeds (Papaver somniferum).

4.2. What are Some Examples of Plant-Derived Drugs?

Many commercial drugs are derived from plants, fungi, or marine microorganisms. Examples include antibiotics like penicillin and erythromycin, the cardiac stimulant digoxin from foxglove (Digitalis purpurea), and salicylic acid, a precursor of aspirin, from willow bark (Salix spp.). Reserpine, an antipsychotic and antihypertensive drug, comes from Rauwolfia spp., and antimalarials like quinine are derived from Cinchona bark.

4.3. How Significant are Natural Products in Cancer Therapeutics?

More than 60% of cancer therapeutics on the market or in testing are based on natural products. Out of 177 drugs approved worldwide for cancer treatment, over 70% are based on natural products or mimetics (Brower 2008). Plant-derived cancer therapeutics include paclitaxel from the Pacific yew tree, camptothecin from the Chinese “happy tree” Camptotheca acuminata, and combretastatin from the South African bush willow.

4.4. What Percentage of Drugs Prescribed Worldwide are Plant-Derived?

About 25% of the drugs prescribed worldwide are derived from plants, with 121 active compounds in use (Sahoo et al. 2010). Between 2005 and 2007, 13 drugs derived from natural products were approved in the United States. Of the 252 drugs on the World Health Organization’s (WHO) essential medicine list, 11% are exclusively plant-derived (Sahoo et al. 2010).

5. Herbal Medicine and the Aging Population

5.1. How Does Aging Affect Physiological Function and Disease Risk?

Aging is associated with a progressive decline in physiological function and an increased risk of pathological changes leading to conditions such as cancer, cardiovascular disease, dementia, diabetes, and osteoporosis. Lifestyle factors, including nutrition and exercise, play a key role in maintaining healthy life quality and duration (Bozzetti 2003; Benzie and Wachtel-Galor 2009, 2010).

5.2. What is the Oxidative Stress Theory of Aging?

The oxidative stress theory suggests that aging is caused by the accumulation of irreversible, oxidation-induced damage resulting from the interaction of reactive oxygen species with the DNA, lipid, and protein components of cells (Harman 1992; Beckman and Ames 1998). Even if aging is unrelated to oxidative stress, many chronic age-related diseases increase oxidative stress (Holmes, Bernstein, and Bernstein 1992; Beckman and Ames 1998; Finkel and Holbrook 2000; Rajah et al. 2009).

5.3. Can Antioxidants in Herbs Provide Therapeutic Effects?

Antioxidants found in herbs may contribute to their therapeutic effects (Balsano and Alisi 2009; Tang and Halliwell 2010).

5.4. Why is Standardization Needed for Herbal Medicine?

With the rising popularity of herbal medicine, traditional identification and preparation methods need to be replaced with more accurate and reproducible methods to ensure product quality, safety, and consistency (see Chapter 20). Given the market value, potential toxicity, and increasing consumer demand, especially among the sick and elderly, the regulation of herbal supplements and medicines is essential.

6. Challenges and Regulations in Herbal Medicine

Harmonizing the market for herbal medicines is fundamental for industry, healthcare professionals, and consumers (Mahady 2001).

6.5. How are Herbal Medicines Regulated in the United States?

In the United States, the Dietary Supplement Health and Education Act (DSHEA) of 1994 classifies herbs, botanicals, and natural concentrates as dietary supplements. These do not require FDA approval before marketing (FDA 2010). Manufacturers are responsible for ensuring the safety and accuracy of claims, although new dietary ingredients may require premarket review for safety.

6.6. How are Herbal Medicines Regulated in Canada?

In Canada, herbal remedies must comply with the Natural Health Products Regulations (Health Canada 2003). All natural products require a product license before sale, which involves providing detailed information on medicinal ingredients, source, potency, and recommended use.

6.7. How are Herbal Medicines Regulated in Europe?

Europe’s Directive 2004/24/EC provides guidelines for herbal medicine use (Calapai 2008). Herbal medicines must be authorized by national regulatory authorities and have a recognized level of safety and efficacy (Calapai 2008). Registration requires evidence of medicinal use for at least 30 years in the EU, with 15 years within the EU.

7. The Importance of Quality, Safety, and Scientific Evidence

7.1. Why is Quality Control Important for Herbal Medicines?

Herbal medicine has been used for disease treatment, prevention, health promotion, and enhancing quality of life. However, there is a lack of systematic assessment for safety and effectiveness. The holistic approach is attractive, but scientific evaluation is challenging. Quality control directly impacts safety and efficacy (Ernst, Schmidt, and Wider 2005; Ribnicky et al. 2008).

7.2. What are the Challenges in Evaluating Traditional Medicines?

There is limited data on the composition and quality of most herbal medicines due to inadequate policies and research methodology (WHO 2001; Kantor 2009). Research on whole herbal mixtures is scarce because the drug approval process does not accommodate undifferentiated mixtures.

7.3. What are the Potential Risks of Using Herbal Medicines?

Some herbal products on the market may be of low quality and suspect efficacy. While herbs are often perceived as safe, they can have side effects, and herb-drug or herb-herb interactions are possible.

7.4. How Can the Efficacy of Botanical Extracts Be Improved?

A major advantage of botanicals is the presence of multiple active compounds that can provide a potentiating effect. However, this presents challenges for separating and identifying active constituents. Standardized botanical extracts must be free of potential hazards, grown under controlled conditions, and originate from a uniform genetic source.

7.5. What Factors Affect the Quality of Botanical Extracts?

The environment can significantly affect phytochemical profiles and efficacy, with temperature, drought, and geographic location playing key roles. Biochemical profiling ensures consistent material use. Improving efficacy by increasing concentration can be counterproductive, necessitating the use of solubilizers and bioenhancers (Ribnicky et al. 2008).

7.6. How Does the Collection of Herbal Materials Impact Biodiversity?

The expanding herbal product market can drive overharvesting of plants, threatening biodiversity. Poorly managed collection and cultivation practices can lead to the extinction of endangered plant species and the destruction of natural resources.

Extensive research is needed into the quality, safety, molecular effects, and clinical efficacy of commonly used herbs. Genomic testing and chemical fingerprinting techniques are available for authentication and quality control. Evidence for the potential protective effects of herbs is often based on in vitro and animal model experiments, supported by epidemiological studies and limited human trials (WHO 2001).

8.2. What Ethical Requirements Should Herbal Medicine Research Meet?

International research should meet the same ethical requirements as all research related to human subjects, including collaborative partnership, social value, scientific validity, fair subject selection, favorable risk-benefit ratio, independent review, informed consent, and respect for subjects (Giordano, Engebretson, and Garcia 2005; Tilburt and Kaptchuk 2008).

8.3. What are the Challenges in Performing Human Studies on Herbs?

The logistics, time, and cost of large, controlled human studies on the clinical effectiveness of an herb are prohibitive, especially when focusing on health promotion. New biomarkers that clearly relate to health outcomes are urgently needed.

8.4. What Other Research Areas Need Attention?

Research is needed to identify active compounds in plants and determine whether whole herbs or extracted compounds are better. Herb-herb and herb-drug interactions require increased awareness and study, as polypharmacy and polyherbacy are common (Canter and Ernst 2004; Qato et al. 2008; Loya, Gonzalez-Stuart, and Rivera 2009; Cohen and Ernst 2010).

8.5. How Can New Technologies Aid Herbal Medicine Research?
