Botanical dietary supplements, a term that often interchanges with herbal supplements, refer to products made primarily from plants or plant parts. They encompass an array of products, from tablets and capsules to liquids and powders. The key feature distinguishing botanical dietary supplements is their sourcing – they originate from the natural constituents of plants, whether that be leaves, stems, flowers, roots, seeds, or bark.
- Botanicals are plants valued for their medicinal or therapeutic properties – herbs are a subset of botanicals.
- Botanical names consist of a Latin genus and a specific epithet. For instance, black cohosh is called Actaea racemosa L.
- To be considered a dietary supplement, botanicals must meet the definition set by the Dietary Supplement Health and Education Act of 1994.
- Botanicals are available in various forms such as fresh or dried plant materials, capsules, tablets, teas, infusions, decoctions, tinctures, and extracts.
- The effects and safety of botanicals can vary. For example, peppermint tea is safe, but peppermint oil can be toxic if misused.
- Scientists use various methods, from history to clinical trials, to evaluate the health benefits and safety of botanical dietary supplements.
- Unlike medicines, botanical dietary supplements don’t require FDA approval before being sold, but their claims must be truthful.
What is a Botanical
Botanical vs. Herbal Products
Botanicals and herbal products often get used interchangeably, but there’s a slight distinction. A botanical refers to any plant or plant part used for its therapeutic or medicinal value. On the other hand, herbal products specifically refer to products derived from herbaceous plants, meaning non-woody plants. So, while all herbal products are botanicals, not all botanicals are herbal products.
Naming and Classification in Botany
In the world of plants, naming and classification are crucial for clarity. Every plant has a scientific name, usually in Latin, which helps distinguish it from others. This binomial nomenclature consists of two parts:
- Genus: Always capitalized and can be used alone to refer to the group.
- Species: Specifies the particular plant within the genus.
For instance, in the name Rosa rubiginosa, Rosa is the genus, and rubiginosa is the species. This precise naming ensures no mix-ups, especially vital when plants have similar common names but different medicinal properties.
Common Examples and Uses
Botanicals are abundant and diverse. Let’s glance at a few and their popular uses:
- Ginkgo biloba: Known to support brain function and improve memory.
- Echinacea: Often taken to boost the immune system.
- Turmeric (Curcuma longa): Used for its anti-inflammatory properties.
- Milk thistle (Silybum marianum): Believed to support liver health.
Botanicals as Dietary Supplements
Botanicals are more than just plants, they often find their way into our diets as supplements. According to the Dietary Supplement Health and Education Act (DSHEA) of 1994, a dietary supplement is a product intended to supplement the diet. It contains one or more dietary ingredients, including vitamins, minerals, herbs or other botanicals, amino acids, and substances such as enzymes, organ tissues, and metabolites. Under this definition, botanicals qualify as dietary supplements when they’re consumed in these forms.
Key Characteristics of Botanical Dietary Supplements
When you’re out shopping for botanical dietary supplements, how do you recognize them? They have distinct characteristics:
- Dietary Ingredients: Botanical dietary supplements contain parts of plants or a combination of plants as their primary ingredient. This could be anything from leaves, stems, and roots to more specialized plant parts like seeds or flowers.
- Intended Use: These supplements are meant to augment your diet. They aren’t drugs and shouldn’t be taken to treat, diagnose, or cure diseases.
- Packaging: These products come labeled as dietary supplements. This labeling differentiates them from conventional foods and drugs.
- Administration: Typically, botanical dietary supplements are taken orally, whether as pills, capsules, tablets, or in liquid form.
