Alagao (Premna odorata): A Treasure in Traditional Medicine



In the heart of the Philippines, where lush vegetation thrives, a humble yet powerful medicinal plant called Alagao (Premna odorata) holds a special place in traditional healing. This remarkable plant, known for its therapeutic benefits, has been used for generations as a natural remedy for various ailments.



Botanical Profile

Alagao is a fast-growing, small tree or shrub that can reach heights of up to 8 meters. It is easily recognized by its broad, heart-shaped leaves with serrated edges, a strong aroma when crushed, and a hairy texture on the underside. The tree produces small, pale-green or yellowish flowers that bloom in clusters, later developing into tiny, dark purple to black fruits.

Belonging to the Lamiaceae family, Alagao thrives in tropical climates, often found in backyards, forests, or even roadsides across the Philippines. Its adaptability and resilience make it a common plant in both rural and urban areas.

Traditional Uses and Therapeutic Benefits

Alagao is often referred to as a "natural pharmacy" because of its diverse health applications. Here are its notable therapeutic properties:

1. Respiratory Relief

The leaves of Alagao are widely used to treat respiratory problems such as asthma, cough, colds, and bronchitis. When boiled to create a decoction or made into a poultice, the plant's expectorant properties help ease breathing and alleviate mucus buildup.

2. Anti-inflammatory and Antiseptic

Alagao leaves contain compounds with anti-inflammatory and antiseptic properties. Applying crushed leaves or decoctions topically can help in wound healing, reducing swelling, and soothing skin irritations like rashes or insect bites.

3. Digestive Aid

For gastrointestinal discomfort, Alagao has been a go-to remedy. Drinking a decoction of its leaves can ease stomachaches, diarrhea, and flatulence. Its carminative properties help expel gas and improve digestion.

4. Antimicrobial Properties

Studies have shown that Premna odorata has antimicrobial activity, making it effective in combating certain bacteria and fungi. This supports its traditional use in treating infections and preventing complications in wounds.

5. Natural Stress Reliever

In aromatherapy, the fragrant leaves of Alagao are valued for their calming and soothing effects, helping reduce stress and promote relaxation.

How to Use Alagao Safely

  • Decoction: Boil 5-7 leaves in 2 cups of water for 10 minutes. Drink the strained liquid for respiratory or digestive issues.
  • Poultice: Crush fresh leaves and apply them directly to the skin for wounds or inflammation.
  • Steam Inhalation: Add leaves to boiling water and inhale the steam to relieve congestion.

Cautions and Recommendations

While Alagao is generally safe for external and internal use, it’s important to consult a healthcare professional, especially for pregnant women, nursing mothers, or individuals with underlying health conditions.

Preserving the Legacy of Alagao

In a world leaning increasingly on synthetic drugs, Alagao reminds us of nature's abundant remedies. Beyond its therapeutic value, it is a testament to the rich ethnobotanical heritage of the Philippines.

Planting and conserving Premna odorata not only ensures access to its medicinal benefits but also contributes to biodiversity and ecological balance. So, whether you're exploring natural remedies or simply appreciating the wonders of local flora, Alagao deserves a spot in your garden and your health regimen.
