The Haldu Tree: The Forest Giant with Powerful Healing Secrets

Haldu Tree
Deep within the forests of South Asia stands a majestic tree, reaching for the sky with a strong, golden-hued trunk. For centuries, its timber has been prized by craftsmen for its durability and beautiful finish. But its true value, known to generations of traditional healers, lies hidden within its heart-shaped leaves and bitter bark.
This is the Haldu Tree (Haldina cordifolia), a botanical powerhouse revered in Ayurveda and folk medicine. Here in Sri Lanka, we know this gentle giant as Kolon (කොලොන්). While its wood builds homes, its medicine helps build health, particularly in one of the most crucial areas of modern wellness: metabolic balance.
Join us as we explore the forgotten healing gifts of the Haldu Tree and learn why this ancient remedy is more relevant today than ever.
A Tree of Many Names (and One Crucial Correction)
To understand the Haldu Tree’s global footprint, it helps to know its various names. However, it’s also vital to clear up a common and significant point of confusion.
- Common English Name: Haldu Tree (derived from its Hindi name).
- Botanical Name: Haldina cordifolia (the universal scientific identifier).
- Ayurvedic/Sanskrit Name: Haridru.
- haidu
An Important Note on the Name “Kadam”: You may sometimes see the Haldu Tree mistakenly referred to as the “Kadam” tree. This is incorrect. The true Kadam or Kadamba Tree is a completely different plant (Neolamarckia cadamba) with immense cultural and religious significance. To find accurate information, it’s essential to use the correct names: Haldu, Haldina cordifolia, or Kolon.
The Ayurvedic Tradition: Haldu for Metabolic Health

For centuries, the primary medicinal use of the Haldu Tree in Ayurveda and other traditional systems has been to support metabolic health, most notably in the management of blood sugar.
The bitter principles found in the bark and leaves are believed to be the source of its power. In traditional medicine, a decoction (a concentrated herbal tea) of Haldu bark is a go-to remedy for individuals struggling with blood sugar imbalances.
It is thought to work by:
- Helping to improve the body’s natural sensitivity to insulin.
- Supporting the healthy metabolism of glucose.
Essentially, traditional healers use it to help the body process sugar more efficiently. This makes the Haldu Tree a subject of great interest for those seeking natural ways to maintain blood sugar levels already within the normal range.
More Than a Single Benefit: Haldu’s Other Healing Gifts
While its effect on blood sugar is its most famous attribute, the healing properties of the Haldu Tree are far-reaching.
1. A Potent Anti-inflammatory and Antiseptic
The bark of the Haldu Tree is a powerful natural antiseptic. Traditionally, a paste made from the bark is applied directly to wounds, sores, and inflammatory skin conditions. It’s believed to reduce redness and swelling, clean the area, and prevent infection, creating an ideal environment for the skin to heal.
2. A Natural Pain Reliever (Analgesic)
Beyond its anti-inflammatory action, Haldu is also used to provide relief from pain. Decoctions of the bark have been used in folk medicine to help reduce fevers and alleviate the general body aches that often accompany them, as well as to soothe rheumatic pain.
3. A Guardian for the Liver
Like many bitter herbs, Haldu is considered a supportive tonic for the liver. In Ayurveda, it’s used to help protect the liver from damage and support its vital, natural detoxification processes. A healthy liver is central to overall health, and Haldu is a traditional tool for keeping it that way.
