What Is Plant-Based Medicine?
There are many approaches to health and wellness—and plant-based medicine continues to gain renewed attention.
At its core, plant-based medicine can be understood in two ways:
The use of plants as part of a healthcare approach
Medicines and products derived from botanical sources
As a practice, it emphasizes the use of herbs, plant extracts, and functional nutrition to support overall well-being. Importantly, it is often used alongside conventional (Western) medicine—not necessarily in place of it.
Today, plant-based ingredients are also widely incorporated into everyday wellness routines—from supplements to skincare, beauty, and personal care products.
Plant-based compounds can be delivered in different ways, including oral (capsules, tinctures, teas) and topical applications, depending on the product and intended use.
It May Go by Other Names
You may encounter several terms used interchangeably with plant-based medicine, including:
Herbal medicine
Botanical medicine
Natural medicine
Traditional or folk medicine
These approaches often overlap with broader systems such as naturopathy, functional medicine, integrative medicine, and traditional practices like Ayurveda and Traditional Chinese Medicine.
You may also hear the term complementary and alternative medicine (CAM)—a category used in conventional healthcare to describe practices outside the mainstream, including plant-based therapies.

A Long History of Plant-Based Medicine
The use of plants for wellness is not new. Across cultures and continents, people have long turned to herbs, flowers, roots, and other botanicals as part of their health and wellness practices.
Long before modern pharmaceuticals, plant-based remedies played a supporting role in both physical and mental well-being. These traditions evolved over generations, often rooted in regional knowledge and guided by observation and experience.
Today, that legacy continues—now complemented by growing scientific interest in how plant-derived compounds interact with the body, including systems such as the endocannabinoid system and the brain—an area of increasing interest in emerging research on cannabis and other plant-based compounds.
Hemp oil extracts in a glass jar also known as green oil. For years, humans have cultivated cannabis for its fiber, seeds, and medicinal properties.
How Plant-Based Medicine Can Support Wellness
There’s no single answer to how plant-based medicine works—because each plant, and each individual, is unique. Every flower, root, and botanical contains its own complex chemistry and range of naturally occurring compounds.
At the same time, no two people respond exactly the same way. Each body has its own biological makeup—including an endocannabinoid system (ECS), which helps regulate functions such as mood, sleep, appetite, and the stress response. As a result, the way plant-based compounds are processed and experienced can vary from person to person.
A Closer Look at Plant-Based Compounds
One of the most compelling aspects of plant-based medicine is the diversity of compounds found in nature. Many plants contain bioactive components—such as phytochemicals, flavonoids, and terpenes—that are being studied for their potential interactions within the body.1
For Example:
Chamomile is commonly used in teas and is associated with calming, relaxation-focused routines
Cannabis contains a wide range of compounds, including cannabinoids like THC and CBD, along with terpenes and flavonoids
Echinacea is often included in seasonal wellness products
Ginger and turmeric are widely used in both culinary and wellness contexts
Lavender is commonly used in aromatherapy for relaxation
Tea tree oil is frequently used in topical formulations
These are just a few examples—there are thousands of plants used across different traditions and applications.

From Traditional Use to Modern Research
Many modern products are derived from or inspired by plant compounds. For example, well-known medications like aspirin and morphine originated from plant sources2—willow bark and poppies, respectively.
Today, both natural medicine and pharmaceutical research continue to explore how plant-based compounds may support wellness and inform the development of new therapies. However, it’s important to note that research varies widely depending on the plant and compound, and not all uses are equally studied or understood.
How Plant Compounds Interact with the Body
Plants contain thousands of naturally occurring compounds, including vitamins, minerals, and phytochemicals. These compounds can interact with the body in different ways—through the skin, bloodstream, and various biological systems, including the endocannabinoid system.3.
For example, when a cannabinoid like CBD is consumed:
It is absorbed into the bloodstream
It interacts with receptors within the endocannabinoid system
This interaction may influence signaling processes related to balance and regulation within the body
Consult with your physician or health care professional about adding CBD to your wellness routine. Functional Medicine and Integrative Medicine Doctors versed in natural and plant based medicine are learning even more about hemp and marijuana plant products with the proliferation of legalization and patient access.
A Balanced Approach to Plant-Based Medicine
While plant-based medicine is often perceived as gentler than many conventional treatments, it’s still important to approach it with care and informed awareness—particularly as interest grows in cannabis and other plant-based compounds.
Possible Considerations
Like any substance—whether food, supplements, personal care products, or medications—plant-based products can cause unintended reactions, including:
Allergies
Sensitivities
Side effects
Potential interactions with medications or other therapies
Because of this, it’s important to take an informed and individualized approach when exploring plant-based options.
Talk to Your Healthcare Provider
If you’re considering plant-based therapies, consult with a qualified healthcare provider—especially if you are managing a health condition, pregnant or nursing, or taking medications.
They can help assess your individual needs, review any potential interactions, and provide guidance on safe and appropriate use. Some plant-based products may not be suitable for certain health conditions, life stages, or in combination with other treatments.
Understanding Regulation and Oversight
Not all plant-based products are evaluated or regulated in the same way. Some are categorized as foods, dietary supplements, or medications, while others fall outside formal regulatory pathways 4.
This underscores the importance of sourcing products from reputable brands and staying informed as regulations evolve.
As interest in plant-based medicine continues to grow, so does the need for clear, accessible education. Regulatory frameworks are evolving alongside research, consumer demand, and broader cultural shifts, which can sometimes create confusion for consumers navigating their options.
How to Get Started With Plant-Based Medicine
If you’re curious about incorporating plant-based approaches into your routine, start by identifying your current needs. This can help guide more informed and intentional choices.
Identify your wellness goals
Research from credible sources
Review product labels carefully
For cannabis, look for third-party lab testing (Certificates of Analysis)
Choose reputable brands and retailers
Keeping a simple journal to track your experiences can also help guide your decisions. From there, a thoughtful, research-driven approach can help you make more confident decisions.
Grow Your Knowledge & Appreciation
Plant-based medicine draws from a long-standing relationship between people and the natural world. Today, it continues to evolve alongside modern science and innovation.
While plant-derived products are widely used in everyday wellness routines, it’s important to approach them with curiosity, care, and credible information. Many people explore plant-based options as part of a broader, integrative approach to health—one that may include both natural and conventional therapies.
If you’re interested in learning more about cannabis and plant-based compounds, exploring foundational topics like the endocannabinoid system, cannabinoids, and product types can be a helpful next step.
