Fo-Ti (Polygonum multiflorum): A Traditional Remedy for Healthy, Lustrous Hair

Fo-Ti, also known in Vietnamese as Hà thủ ô, is a well-known herb in traditional Eastern medicine, widely used to reduce hair loss, stimulate hair growth, and improve overall hair health. For centuries, people have relied on this natural remedy to treat issues such as premature graying, thinning, and weak hair. Beyond its cosmetic benefits, Fo-Ti also offers numerous advantages for general health and vitality.

What Is Fo-Ti?

Fo-Ti (scientific name Polygonum multiflorum Thunb.) is also called He Shou Wu in Chinese medicine. In Vietnam, it is known by several local names, including dạ giao đằng, má oản, khua lình (Thai), xạ ú sí (Dao), and mằn năng ón (Tày).
The herb comes in two main varieties — white Fo-Ti and red Fo-Ti. Among the two, red Fo-Ti is more commonly used in traditional remedies because it is believed to be more potent and beneficial.

Health Benefits of Fo-Ti

1. Nourishes the Liver and Kidneys, Strengthens the Body

The root of Fo-Ti helps stimulate the production of red and white blood cells, which supports blood circulation and boosts energy levels. In traditional medicine, it is used to treat symptoms like fatigue, insomnia, lower back pain, and weakness in the knees—conditions often associated with liver or kidney deficiency.
Modern studies also suggest that Fo-Ti contains compounds with antioxidant properties that can help combat oxidative stress, one of the key contributors to aging and chronic diseases.

2. Promotes Hair Growth and Prevents Premature Graying

One of the most famous uses of Fo-Ti is its ability to restore natural hair color and promote hair growth. Premature graying often occurs due to stress, nutrient deficiency, or aging. Fo-Ti nourishes the scalp and strengthens hair follicles by improving blood flow and restoring balance to the liver and kidneys — organs believed in Eastern medicine to govern hair health.
Regular use of Fo-Ti can make hair softer, darker, and shinier over time. It also helps repair damaged strands and may reduce split ends and dryness caused by environmental factors or chemical treatments.

3. Enhances Immunity and Supports Longevity

Fo-Ti is considered a rejuvenating tonic. It strengthens the body’s immune response, enhances energy levels, and helps fight viral and bacterial infections. When taken regularly (in proper doses), it can help maintain vitality, reduce dizziness, calm palpitations, and promote restful sleep.
In Chinese herbalism, Fo-Ti is often classified as a “longevity herb,” believed to restore youthfulness and delay the effects of aging.

4. Improves Skin Health

Because Fo-Ti aids in liver detoxification, it can help clear skin issues such as acne, itching, or dullness caused by internal toxins. The herb’s blood-enriching effect also contributes to a rosy complexion and improved skin elasticity. Its natural antioxidants help slow down the visible signs of aging, giving the skin a more radiant and youthful appearance.

Potential Toxicity and Precautions

Raw Fo-Ti contains natural compounds called anthraquinones, which have a strong laxative effect. Consuming the herb without proper processing can lead to diarrhea, abdominal pain, fatigue, or mild poisoning symptoms. Therefore, traditional preparation methods are essential to reduce its toxicity.

After being steamed or boiled with black beans (đậu đen), ginger, or licorice root, most of the harmful compounds are neutralized, making the herb safe for long-term use.
Raw Fo-Ti is typically used only for short-term treatments such as relieving constipation, treating boils, or lowering fever — not for internal tonics or beauty care.

People with liver disease, chronic diarrhea, or weak digestion should avoid using raw Fo-Ti. Always consult a healthcare professional before consuming it as a supplement.

Popular Ways to Use Fo-Ti for Hair and Skin

1. Fo-Ti Soaked in Honey

Ingredients:

• 100g sliced red Fo-Ti root

• 200g pure honey

Place the Fo-Ti slices in a glass jar and pour honey over them until fully covered. Let the mixture sit for about three months before using. Take 2–3 teaspoons of the infused honey, mix with warm water (around 60°C), let it steep for 5 minutes, and drink daily.
This tonic helps nourish the hair from within, strengthens the body, and promotes better skin hydration.

2. Fo-Ti and Black Sesame Mixture

Dry and finely grind both Fo-Ti root and black sesame seeds. Store the mixture in an airtight container.
Take 2–3 teaspoons daily, mix with honey, and consume directly or with warm water. This combination provides a natural source of essential fatty acids and antioxidants, helping maintain dark, shiny hair and smooth skin.

3. Fo-Ti Cooked with Black Beans

Ingredients:

• 1kg Fo-Ti (fresh or dried)

• 2kg black beans

Boil the black beans until soft, yielding about 1.5 liters of broth. Add the Fo-Ti roots and simmer over low heat for several hours, adding more bean broth as needed.
After cooking for a full day, remove the roots, dry them, and grind into a fine powder. Store the powder in a sealed jar and consume 2–3 teaspoons daily with warm water or honey.
This traditional preparation method helps reduce the herb’s toxicity and enhances its nourishing effects on hair and the body.

4. Herbal Fo-Ti Hair Rinse

Ingredients:

• 50g Fo-Ti root

• 5 roasted soapberries

• 5 stalks of lemongrass

Boil all ingredients in 2 liters of water for several minutes, then let the mixture cool. Use this water as a natural shampoo or rinse. Apply 2–3 times a week for at least one month to achieve healthier, shinier, and stronger hair.

Modern Applications and Tips

Today, Fo-Ti can be found in capsule, powder, or tonic form, often combined with other herbs like ginseng, goji berries, or dong quai to enhance its rejuvenating effects. When used responsibly and prepared correctly, Fo-Ti remains one of the most valued herbal remedies for anti-aging, hair health, and overall wellness.

However, as with any natural supplement, consistency and moderation are key. Always ensure that the Fo-Ti you use is processed (cooked) Fo-Ti, sourced from reputable suppliers.
