Herbal Medicine Effectiveness: Overview and General Evidence
Herbal medicine is widely used around the world and has been shown to be effective for certain health conditions. Research shows that herbal remedies can be tested for effectiveness using the same methods as conventional drugs, and several specific herbal extracts have demonstrated benefits for particular diseases or symptoms 13. However, the effectiveness of herbal medicine can vary depending on the condition being treated, the quality of the herbal product, and the specific formulation used 134.
Herbal Medicine for Mental Health: Depression
Chinese herbal medicine (CHM) has been studied for its effects on depression. Systematic reviews and meta-analyses of randomized controlled trials found that CHM alone was more effective than placebo in reducing depression symptoms and had similar effectiveness to standard Western medications. When CHM was combined with conventional treatments, patients experienced even better outcomes and fewer side effects compared to using Western medications alone .
Herbal Medicine for Infectious Diseases: COVID-19
During the COVID-19 pandemic, studies found that combining herbal medicine with Western medicine improved recovery rates, reduced symptoms like cough and fatigue, and did not increase serious side effects. However, more high-quality research is needed to confirm these findings and to better understand the safety of herbal treatments for COVID-19 .
Herbal Medicine for Cardiovascular Diseases
Herbal medicines have shown promise in treating cardiovascular diseases (CVDs) such as coronary heart disease and heart failure. Clinical studies and reviews report that certain herbal formulas can improve heart function, reduce symptoms, and target multiple disease mechanisms, including inflammation and oxidative stress. Herbs like Ginseng, Ginkgo biloba, Ganoderma lucidum, and Gynostemma pentaphyllum have been studied for their potential benefits in CVDs, but safety and possible interactions with other drugs remain important concerns 910.
Herbal Medicine for Immunity
Some herbal remedies, such as Echinacea, Sambucus nigra, and Pelargonium sidoides, are used to support immune function. These herbs may help boost immunity, especially in people with weakened immune systems due to malnutrition or chronic illness. However, claims of creating an "invincible" immune system are not supported by current evidence .
Herbal Medicine for Hormonal Health: Testosterone
Herbal supplements like Tribulus terrestris, Fenugreek, and Ashwagandha are sometimes used to manage testosterone levels. Research shows mixed results, with some studies reporting modest improvements and others finding no significant benefit. Safety and potential interactions with conventional medications should be considered, and more research is needed to establish clear guidelines .
Challenges in Evaluating Herbal Medicine Effectiveness
The effectiveness of herbal medicine is sometimes difficult to assess due to the complexity of herbal mixtures, unclear active ingredients, and variability in product quality. New research methods, such as metabolomics, are being developed to better understand how herbal medicines work and to identify their active compounds . Cost-effectiveness and safety, including the risk of side effects and interactions with other drugs, are also important factors to consider 410.
Conclusion
Herbal medicines can be effective for certain health conditions, including depression, some infectious diseases, cardiovascular diseases, and immune support. Their effectiveness depends on the specific herb, condition, and formulation. While some herbal remedies are supported by scientific evidence, others require more research to confirm their benefits and safety. It is important to use herbal medicines with caution, be aware of possible side effects and interactions, and consult healthcare professionals for guidance.
