What Are Herbal Actions?

Herbal actions refer to the specific, measurable effects that herbs have on different systems, organs, or tissues within the body. These actions describe what an herb is traditionally used for and how it helps manage or treat various ailments. For instance, some herbs are known for their ability to relieve pain (analgesics), while others may boost the immune system (immunomodulators) or calm the nerves (nervines). Understanding these actions is crucial for anyone using herbs therapeutically, as it guides the selection and combination of herbs to achieve the desired health outcomes.


The study and application of herbal actions form the core of herbal medicine, making it distinct from other forms of medicine. Herbalists use this knowledge to tailor treatments to individual needs, considering the unique qualities of each herb. This approach not only aims to alleviate symptoms but also addresses the root causes of illness, promoting holistic healing and balance within the body. As we explore further, a detailed chart will help illustrate these actions, providing a clear framework for their practical use in herbalism.


The Basics of Herbal Actions


Herbal actions are foundational to practical herbalism. They offer a framework for predicting how an herb will interact with the body, aiding in the creation of tailored herbal remedies that ensure safety and efficacy. This framework is not just about identifying single effects; it's about understanding a holistic view of how multiple herbal actions can synergistically influence health. By grasping the different properties of herbs—from their ability to calm or stimulate, to heal or detoxify—herbalists can formulate remedies that are finely tuned to the needs of individual patients.


Understanding True Herbal Actions

In the study of herbalism, terms like "anti-inflammatory" or "antibiotic" are often mistakenly referred to as herbal actions, but they more accurately describe the effects or outcomes of herbal actions. True herbal actions specifically denote how an herb functions on various organs and systems within the body, influencing physiological or biochemical pathways directly. For example, while "anti-inflammatory" describes the result of using certain herbs, the actual action might be "circulatory stimulant," which improves blood flow and reduces inflammation as a secondary effect.


Common misattributions such as "antispasmodic" or "antimicrobial" also describe outcomes rather than actions. True herbal actions include "diaphoretic," which promotes sweating to reduce fever; "carminative," which aids in relieving digestive gas; or "nervine," which acts specifically on the nervous system to calm or stimulate. Understanding these distinctions is crucial for accurately applying herbal knowledge in practice, ensuring that practitioners are addressing the root causes of ailments through direct, targeted action on the body's own systems and organs.


Understanding Herbal Actions Chart


To better understand the concept of herbal actions clearly, let's look at a simple herbal actions chart. This chart categorizes common herbal actions and provides examples of herbs that possess these actions:

This chart is a basic tool that can guide you in selecting herbs based on their primary actions. Of course, there are many more herbs for each of these categories, and some herbs can have multiple herbal actions. For example, nettle is known to be an alterative as well as a tonic herb, and ashwagandha is both a tonic and adaptogen. 


Part of the art of making herbal remedies involves selecting the right herb(s) to match the specific illness being treated. For example, if a remedy calls for a carminative and a diaphoretic, instead of using two separate herbs, one could simply use ginger as this contains both herbal actions. 


Tonic Herbs in Western vs. Eastern Herbalism


In herbalism, the concept of tonic herbs, although shared between Western and Eastern traditions, varies significantly in its application and focus. In Western herbalism, tonic herbs are primarily regarded as substances that restore, nourish, and support the overall health of the body. They are often used to strengthen specific organs or systems, such as the liver or digestive tract, and to enhance general vitality. Examples include nettle and dandelion. 


Conversely, in Eastern herbalism, particularly in Traditional Chinese Medicine (TCM), tonic herbs are categorized based on their energetic qualities and targeted actions on the body's vital energy, or Qi. These tonics are further subdivided into categories like Qi tonics, blood tonics, and yin or yang tonics, each with specific roles such as boosting energy, enriching blood, or balancing internal heat and cold. Examples of herbs from TCM include ginseng and astragalus, which are used with precision to address distinct imbalances and promote harmony within the body's systems. Thus, while both traditions recognize the strengthening and balancing properties of tonics, Eastern herbalism employs a more holistic and energetically integrated approach.


Exploring the List of Western Herbal Actions



Western herbalism features an extensive list of herbal actions, each with specific effects and applications. Here's an overview of the primary herbal actions:


  • Adaptogens: These herbs help the body adapt to stress, supporting stamina and endurance. They are uniquely balancing and help restore overall harmony.

Cholagogues are especially useful in improving overall digestive health and can help in the treatment of gallstones and other bile-related disorders.
  • Demulcents: Particularly beneficial for soothing the digestive and respiratory tracts, these herbs are rich in mucilage.

Practical Application of Herbal Actions


Understanding herbal actions allows herbalists to skillfully combine herbs to address various facets of a health condition effectively. For instance, in treating a common cold, an herbalist may choose elderberry for its antiviral properties, echinacea to boost the immune system, and mullein to alleviate congestion. Additionally, an herbalist might include ginger to warm the body and promote sweating, helping to break a fever. This strategic combination of herbs not only aims to relieve symptoms but also supports the body's natural healing processes, showing the depth of strategy involved in herbal medicine.


Considerations When Using Herbs


While herbs are natural, they are not without potential side effects. It's crucial to consider possible interactions with medications, be aware of allergies, and recognize that natural does not always mean safe, especially at high doses or when used improperly. For example, certain herbs like St. John's Wort can interfere with the effectiveness of prescription medications, including antidepressants and birth control pills. (1Additionally, herbs such as comfrey and kava can cause liver damage if used inappropriately. (2, 3) Thus, it's important for users to consult with healthcare providers, particularly when integrating herbs with other treatments or when addressing serious health conditions.




Herbal actions provide a foundational understanding crucial for effective herbalism practice. By understanding what each herbal action entails, practitioners can make informed choices about which herbs to use, appropriate dosages, and optimal administration methods. Whether you are a professional herbalist or a DIY enthusiast, deepening your understanding of herbal actions will enhance your ability to use herbs safely and effectively. As always, consulting with a professional herbalist or healthcare provider before starting any new herbal regimen is advised.


Herbalism offers a path to natural healing and wellness, and with a firm grasp of herbal actions, you are well-equipped to navigate this path with confidence and expertise.
