Phytotherapy, naturopathy, targeted diet, mindfulness meditation: the approaches grouped under the term natural healing cover a wide spectrum. Their common point lies in the use of non-drug methods to relieve common ailments. Since 2023, Inserm and HAS have been evaluating several of these practices according to criteria of efficacy, safety, and methodological quality, which redraws the boundary between traditional remedy and validated care.
Non-drug interventions: what scientific evaluation changes
The term “alternative medicine” encompasses dozens of disciplines, but not all benefit from the same level of evidence. Inserm and HAS now classify certain approaches as evaluated non-drug interventions, with a methodological framework comparable to that of clinical trials.

This classification distinguishes practices according to their degree of validation. To better understand the principles of natural healing, one must first accept that not all methods are equal in light of the available data.
| Approach | Validation Level (Inserm/HAS) | Main Documented Use |
|---|---|---|
| Acupuncture | Evaluated, integrated into certain care pathways | Chronic pain, nausea |
| Mindfulness meditation | Evaluated, positive results on stress markers | Anxiety, prevention of depressive relapses |
| Adapted physical activity | Recommended by HAS | Hypertension, joint pain, fatigue |
| Medical hypnosis | Evaluated, used in hospital settings | Pain management, preparation for procedures |
| Phytotherapy (medicinal plants) | Variable depending on the plant and indication | Digestive disorders, sleep, common ailments |
| Low FODMAP diet | Validated by clinical studies | Irritable bowel syndrome |
The gap between the “validation level” columns is significant. Acupuncture and meditation have meta-analyses published in indexed journals. Phytotherapy, on the other hand, presents a very heterogeneous level of evidence from one plant to another.

Phytotherapy and naturopathy: two distinct logics of natural care
These two terms are often confused. Phytotherapy refers to the use of medicinal plants to treat a specific symptom (valerian tea for sleep, turmeric extract for inflammation). The naturopath, on the other hand, offers a holistic approach that integrates diet, physical activity, stress management, and sometimes phytotherapy as one tool among others.
A naturopath does not prescribe medication. Their role is to establish a vitality assessment and suggest lifestyle adjustments. In France, this profession is not regulated by a state diploma, which means that the quality of training varies significantly from one practitioner to another.
Medicinal plants: the trap of self-medication
Essential oils illustrate this risk well. Their concentration of active ingredients makes them effective, but also potentially dangerous in cases of incorrect dosage, drug interactions, or use in pregnant women. Contrary to popular belief, “natural” does not mean “risk-free”.
- Some plants (St. John’s wort, grapefruit) alter the absorption of common medications such as anticoagulants or oral contraceptives
- Pure essential oils applied to the skin without dilution can cause burns or allergic reactions
- Herbal supplements sold online sometimes escape the quality controls applied in pharmacies
Before incorporating a plant into their care routine, the most reliable reflex remains to consult a healthcare professional who is knowledgeable in both conventional pharmacology and phytotherapy.
Diet and natural healing: the example of the FODMAP diet
The low FODMAP diet is one of the best-documented cases of a dietary method for therapeutic purposes. Recommended for individuals suffering from irritable bowel syndrome, it is based on the temporary elimination of certain fermentable carbohydrates (excess fructose, lactose, polyols, fructans, galacto-oligosaccharides).
The Santé.fr website, managed by the Ministerial Delegation for Digital Health, specifies that this diet should remain temporary and supervised by a professional. A gradual reintroduction phase is necessary to identify the truly problematic foods and preserve the diversity of the gut microbiota.
Hypertension and non-drug measures
Recent recommendations for managing high blood pressure increasingly emphasize so-called “natural” measures: reducing salt intake, regular physical activity, stress management, increasing potassium intake through fruits and vegetables. These measures do not replace antihypertensive treatment when necessary, but they form the foundation of prevention and long-term blood pressure control.
Safeguards for a coherent natural care pathway
The integration of natural methods into a health pathway requires some precautions that public guides often overlook.
- Systematically inform your primary care physician of any use of phytotherapy or dietary supplements to avoid interactions
- Prefer practitioners whose training is verifiable (university certificates in phytotherapy, inter-university diplomas in integrative medicine)
- Beware of promises of total healing for serious conditions (cancer, autoimmune diseases): no natural approach replaces a validated medical treatment in these situations
- Check the origin and traceability of natural products, especially for essential oils and imported supplements
Natural healing is gaining credibility as research distinguishes what works from what is based on belief. The decisive criterion remains the quality of the scientific evaluation behind each method, not its age or popularity.
