What is saw palmetto and why is it used in phytotherapy?
Saw palmetto (Serenoa repens), also known as sabal or saw palmetto, is a plant native to North America. Its berries, rich in active compounds, have been used in herbal medicine for centuries to support prostate health, regulate hormones and promote hair growth.
Renowned for its anti-inflammatory, diuretic and hormone-regulating properties, this plant is particularly recommended for men suffering from benign prostatic hyperplasia (BPH) and for those prone to hormonal hair loss.
What are the benefits of saw palmetto for the prostate?
Saw palmetto is mainly used for prostate well-being, thanks to its effects on the following areas:
Reduction of benign prostatic hypertrophy (BPH): it limits the proliferation of prostate cells and reduces urethral compression.
Improved urinary comfort: It reduces frequent urges to urinate, especially at night (nocturia), and improves urinary flow.
Anti-inflammatory action: soothes prostatic inflammation and reduces associated pain.
Natural alternative to medicated treatments: Unlike certain allopathic drugs, it acts without notable side effects such as reduced libido or erectile dysfunction.
Its effectiveness is based on its fatty acids and phytosterols, which inhibit the conversion of testosterone into dihydrotestosterone (DHT), a key factor in prostatic hypertrophy.
Is saw palmetto effective against hair loss?
Yes! saw palmetto extract is recognized as a natural treatment for androgenetic alopecia, the leading cause of hormonal hair loss in men and women. It works by:
Blocking production of DHT, a hormone responsible for shrinking hair follicles.
Improving blood circulation to the scalp, for better hair follicle nutrition.
Slows hair loss and stimulates progressive regrowth.
Available in the form of dietary supplements, hair lotions and shampoos, it is a natural alternative to medicated treatments such as finasteride, often associated with undesirable side effects.
Does saw palmetto have an impact on female hormones?
Saw palmetto is sometimes used in women to :
Regulate hormonal imbalances linked to excess androgens, notably in cases of polycystic ovary syndrome (PCOS).
Alleviate hirsutism (excessive hair growth) caused by excess testosterone.
Reduce hormonal acne, often linked to sebum overproduction and androgen hypersensitivity.
However, its use must be carefully supervised, as it can interact with hormonal contraceptives and fertility treatments.
Does saw palmetto boost male libido and vitality?
Yes, saw palmetto is often considered a natural male tonic. Thanks to its testosterone-regulating effects, it can help to:
Support a balanced libido, especially in men suffering from age-related hormonal decline.
Enhance vitality and stamina, by acting on the body's general energy level.
Improve erectile function, although studies on this subject remain limited.
How should saw palmetto be consumed to reap its full benefits?
Saw palmetto is available in several forms, adapted to different needs:
Capsules or tablets: The most common form, with a standardized dosage of fatty acids for optimal action.
Mother tincture or liquid extract: dilute in water or herbal tea for rapid absorption.
Infusion: Less concentrated, but useful for its diuretic and draining effects.
Local application (shampoo, lotion): For targeted action on the scalp and hair loss.
Recommended dosage
Benign prostatic hyperplasia: Approx. 320 mg standardized extract per day.
Hair loss: Between 160 and 320 mg per day, in addition to a suitable hair care routine.
Female hormonal balance: 160 mg daily, to be adjusted according to the recommendations of a health professional.
Are there any contraindications to using saw palmetto?
Although saw palmetto is well tolerated, certain precautions are necessary:
Not recommended for pregnant and breast-feeding women, as it can influence hormone levels.
Avoid when taking anticoagulants, as it may slightly thin the blood.
Possible interaction with hormonal treatments, particularly contraceptives and replacement therapies.
Rare side effects, such as mild digestive disorders (nausea, diarrhea) or headaches.
It is advisable to seek the advice of a health care professional before starting a cure, especially if you are undergoing medical treatment.
How to choose quality saw palmetto and where to buy it?
To take full advantage of its benefits, it's essential to choose a saw palmetto extract standardized in fatty acids (between 85 and 95%).
In pharmacies and parapharmacies: for safe, certified food supplements.
In organic stores and phytotherapy stores: For natural, organic products.
On specialized websites: Be sure to check the composition, origin and concentration of active ingredients before you buy.
Always choose products bearing a quality label, guaranteeing chemical-solvent-free extraction and optimum concentration of active plant ingredients.
