What is Habb-ul-As?

Habb-ul-As refers to the small, dark blue-black berries of Myrtus communis, the common myrtle shrub native to the Mediterranean basin and widely naturalized across the Middle East and South Asia. In Unani medicine — the Greco-Arabic healing tradition — it has been prescribed for over two millennia by physicians including Ibn Sina (Avicenna), who detailed its uses in the Canon of Medicine. The berry is classified as a qaabiz (astringent) and muqawwi (strengthening) agent, prized for toning tissues, drying excessive secretions, and protecting the body against infection.

How does Habb-ul-As work?

Myrtle berries are exceptionally rich in tannins and polyphenols, which bind to proteins on mucosal surfaces and create an astringent effect that firms tissues, slows intestinal motility, and reduces fluid loss — explaining its traditional use in diarrhea. The essential oil fraction, particularly 1,8-cineole and myrtucommulone, has demonstrated meaningful antimicrobial and anti-inflammatory activity, which supports its traditional roles in respiratory, urinary, and skin conditions. Anthocyanins and flavonoids contribute antioxidant protection, helping to reduce oxidative stress in tissues throughout the body.

What forms does Habb-ul-As come in?

Traditional Unani preparations use the dried whole berry in decoctions or as a finely ground powder taken with water or honey. Powdered berry is also applied topically as a paste for scalp and skin conditions. Modern preparations include standardized capsules and topical hair oils infused with myrtle extract. For digestive use, decoction or powder is most common; for hair and scalp, topical oil preparations are preferred.

Where it comes from:

Myrtle has been sacred in multiple cultures — venerated by ancient Greeks and Romans, mentioned in the Hebrew Bible, and recorded by Dioscorides in De Materia Medica (1st century CE). In Unani medicine, Ibn Sina's Canon of Medicine (~1025 CE) lists it for diarrhea, excessive sweating, strengthening the stomach, treating dandruff and hair loss, and managing urinary complaints. It remains an active ingredient in licensed Unani formulations in India, Pakistan, and Iran to this day.

What does Habb-ul-As help with?

• Diarrhea and loose stools: Myrtle berry's high tannin content acts as a natural astringent in the gut, helping to firm the intestinal lining and slow the passage of stool. This is its most well-documented traditional use, and modern studies on myrtle extracts have confirmed antimicrobial activity against several bacteria that commonly cause diarrhea.
• Hair loss and thinning hair: Applied topically or taken orally, myrtle berry is traditionally used to strengthen hair roots and reduce shedding. Its antimicrobial and anti-inflammatory compounds help address scalp infections and inflammation — two common but overlooked contributors to hair thinning. Unani practitioners have prescribed it for hair loss for over a thousand years.
• Dandruff and scalp conditions: The antimicrobial and astringent properties of myrtle berry help control the fungal and bacterial overgrowth that drives dandruff and seborrheic scalp conditions. Topical application as a paste or infused oil is the traditional approach, and it helps reduce scalp oiliness, flaking, and irritation.
• Excessive sweating (hyperhidrosis): Ibn Sina specifically noted myrtle's ability to reduce excessive secretions, and it has been used for centuries to manage abnormal sweating. Its astringent tannins work by toning sweat glands and tightening pores, offering a gentler alternative to conventional antiperspirants.
• Urinary tract infections (mild/recurrent): Myrtle berry has traditionally been used to support bladder and urinary tract health. Its antimicrobial essential oil components and flavonoids help inhibit the bacteria most commonly responsible for UTIs, and its mild diuretic action promotes flushing of the urinary tract.
• Respiratory infections and cough: The 1,8-cineole in myrtle's essential oil is a well-recognized expectorant and antimicrobial agent, and myrtle has been traditionally used to ease coughs, bronchitis, and upper respiratory infections. It helps loosen mucus and inhibit the pathogens that cause respiratory illness.
• Digestive weakness and bloating: Beyond diarrhea, myrtle berry is considered a general digestive tonic in Unani medicine — it helps settle the stomach, reduce gas, and improve overall digestive tone. Its bitter and astringent qualities stimulate digestive secretions while calming irritated gut tissue.
• Skin wound healing: Applied topically, myrtle berry paste has been used to support wound healing, reduce skin inflammation, and protect against infection. Its tannins promote tissue contraction and barrier restoration, while antimicrobial compounds help keep wounds clean.
• Oral health and gum disease: Traditional Unani dental preparations include myrtle berry for strengthening gums and reducing oral infections. Its tannins tone gum tissue and its antimicrobial compounds inhibit oral pathogens, supporting both gum health and fresh breath.

What can Habb-ul-As help prevent?

• Recurrence of mild diarrheal episodes with ongoing use
• Scalp infections that can accelerate hair loss

Which foods are rich in Habb-ul-As?

1. Fresh myrtle berries
2. Myrtle berry jam or conserve
3. Pomegranate
4. Blueberries and dark berries
5. Green tea

Practical Tips:

Myrtle berries are rarely available as a fresh food outside Mediterranean and Middle Eastern regions, making the dried berry powder or decoction the most practical form for most users. Supporting your diet with other tannin- and polyphenol-rich foods (pomegranate, dark berries, green tea, black tea) will complement and reinforce myrtle's key mechanisms.

What are the side effects of Habb-ul-As?

• Mild nausea or stomach upset at higher doses
• Constipation with excessive use (due to strong astringent effect)
• Allergic skin reaction if applied topically in sensitive individuals
• Reduced iron absorption if taken with meals (tannin binding)
• Not recommended during pregnancy (traditional caution for uterine tone)

Good to know:

Habb-ul-As has a long history of safe traditional use at standard doses and is generally well tolerated. Most side effects are dose-dependent and mild. It should be avoided in pregnancy due to theoretical uterine-stimulating effects reported in traditional literature, and used cautiously in young children.

How much Habb-ul-As should you take?

• Recommended daily: 3–5 grams of dried berry powder per day in traditional Unani practice; modern encapsulated extracts typically standardized to 250–500 mg standardized extract (equivalent to 2–4 g whole berry) taken once or twice daily.
• Best time of day: Morning and evening doses are traditional; for digestive use, take before or with meals.
• With or without food: Best taken with a small amount of food or warm water to reduce risk of stomach upset; avoid taking with iron-rich meals due to tannin-iron binding.
• Time to effect: Digestive effects (diarrhea, bloating) within 2–5 days; hair and scalp benefits typically noticeable after 4–8 weeks of consistent use; antimicrobial/urinary effects within 1–2 weeks.
• How long to take it: Traditional use allows ongoing long-term use at standard doses for chronic conditions (hair loss, digestive weakness). For acute conditions (diarrhea, UTI), use for 5–14 days and reassess. No formal cycling protocol is established, but periodic breaks of 2–4 weeks are a sensible precaution with prolonged use.
