Plants have had a long history of medicinal use and are still in high demand around the globe.   Plants that are used in whole or in part for their therapeutic properties are called botanicals and products that are made from plants are sometimes phytomedicines.    Medicinal herbs are considered a subset of botanicals.  All of the plants and herbs have common and scientific names.

Products made from plants are sold in many forms: fresh or dried; liquid or solid extracts; tablets, capsules, powders; tea bags; and other forms.  For example, fresh ginger root is often found in the produce section; dried ginger root is sold packaged in tea bags, capsules, or tablets; and liquid preparations are also made from ginger root and sold.   When ginger and other botanicals are manufactured and sold in tinctures, capsules, or tablets, they are considered dietary supplements and are subject to DSHEA and other state and federal regulations.    Botanicals are also sold in topical oils, creams, and salves, which are typically found in the Health & Body Care (HBC) area of a natural product store.

Herbs, a subset of botanical products, are sold as single (individual) herbs and also in many combinations.  The combinations can include multiple herbs, and may also include combinations of vitamins, minerals, and other specialty ingredients.  Usually, these combinations are designed to provide help for a variety of health conditions and support for various systems, functions, and organs of the body.   The categories of combination products range from gender and age-related to mood and wellbeing; from joints and ligament support to cardiovascular and urinary support and many more. 

Botanical raw materials originate from many different places around the world.  Cultivated herbs that are farmed for mass production may be genetically modified and are usually sprayed with insecticides, pesticides, and fungicides.  They may also be fumigated with sulfur dioxide to prevent spoilage caused by bugs and mold.  Exposure to sulfur dioxide can cause a reaction in people who have sulfur or similar sensitivities to fumigated herbs.    Most of the raw materials botanical manufacturers produce for natural product stores, however, are grown organically.  If they are grown in the United States they are subject to national organic standards and may be certified; if the raw material is sourced from outside the United States, the manufacturer is responsible for verification of organic standards as touted by the supplier.  All finished products must have organic ingredients certified by agencies approved by the USDA in order to use the USDA Organic seal. 

Why this matters:

Recent scandals regarding the legitimacy and safety of raw material from China that is labeled as organic have caused consumers to become more focused on the sources of the raw materials contained in their nutritional supplements.  In addition, there is growing awareness and concern about GMOs that may be found in nutritional supplements and herbs.  Many natural product customers want organic or wild-crafted herbs and will look for products with the organic seal or Wild-Crafted language on the bottle.

The third source of herbs and plants are those that are picked from their natural or indigenous habitat.  These are called wild-crafted herbs.  Although they are not grown or cultivated by men, their habitats can be damaged during the harvesting.   Herbs that are labeled Responsibly Wild Crafted, however, use sources that adhere to best practices for harvesting wild herbs including:

  • Assuming responsibility for what is harvested
  • Making positive identification of plants before they are gathered
  • Investigating the health of the ecosystem and the plant population before harvest
  • Not gathering more than needed
  • Harvesting only in appropriate habitats, never in vulnerable environments
  • Wearing proper clothing and using the correct tools when harvesting; minimizing any injury to the site
  • Obtaining written permission from the landowner before entering the land, OR harvesting on the wildcrafter's own land 

Why this matters:

If a manufacturer uses the word standardized to mean their manufacturing procedures are the same for all their products, they are using the term incorrectly.  The correct use of the term, especially when it is printed on the product label, tells the customer that the amount of the active ingredient in the product is a consistent amount in all the products regardless of the source of the raw materials.

Since the sources of medicinal botanicals can vary from place to place and year to year, many herbal manufacturers use a process called standardization to ensure batch-to-batch consistency of their products.  This process involves measuring the number of chemicals or compounds (known as markers) that are believed to be the active agents and ensuring that each product has the same amount or concentration of these active ingredients.   This voluntary quality control process is not required by any legal or regulatory agency.   As a result, the standardized process may vary from manufacturer to manufacturer.  

There are hundreds of known botanicals in use around the world.   The following list of forty medicinal herbs and botanicals that were the highest sellers in the United States in 2012, the latest year of available data[1], ranked in order of highest to lowest.

Words to Remember


Is one of the oldest systems of medicine and health care that originated in northern India over 3,000 years ago. Based on the Sanskrit words ayur (life) and veda (science or knowledge), Ayurvedic Medicine promotes the use of herbal compounds, special diets, and other traditional healing practices.



Describes the substances that come from plants that are used in nutritional supplements and natural body care products.



Medicines made from plants. These medicines can be either pharmaceuticals (drugs) or nutraceuticals (nutritional supplements) that provide health-giving ingredients and medicinal benefits.



Polyphenols are antioxidants. There are different types of polyphenols: phenolic acids found in tea, coffee, blueberries, plums, apples, and cherries; flavonoids (also an anti-inflammatory agent) found in many different fruits and vegetables, legumes, red wine, and green tea; stilbenes found in red wine and resveratrol; and lignans found in legumes, cereals, grains, fruits, algae, and some vegetables.



The process a manufacturer uses to ensure consistency in the amount of the active ingredients in nutritional supplements produced from ingredients obtained from a variety of sources.



Sometimes called TCM, Traditional Chinese Medicine is a variety of medical and health care practices that are based on traditions for over 2000 years practiced in China, including herbal medicine, acupuncture, massage, exercise, and dietary therapies.



Describes the harvesting process for herbs and plants that grow in the wild of nature without human intervention. Most wildcrafting harvesters follow specific guidelines intended to protect the future growth of the plants in the wild and the environment in which the plants are growing.
