Availability
Oroxylum indicum is native to India, China, and Southeast Asian countries like Malaysia, Laos, Thailand, and Vietnam. It's typically found in deciduous forests at altitudes up to 1,000 meters. The tree can be found in a variety of habitats, including moist and dry tropical forests, and is often cultivated for its ornamental and medicinal value. Due to its widespread use and slow growth, it's becoming endangered in some regions, and efforts are being made to conserve it. The plant's various parts—including the bark, roots, and seeds—are available in traditional medicine markets, often in dried or powdered form.
External Look
The Oroxylum indicum tree is easily recognizable by its unique features: Tree: It's a medium-sized, erect, deciduous tree with a light grey or brownish bark that's corky and fissured. It has a sparsely branched trunk. Leaves: The leaves are one of the most distinctive features. They are exceptionally large, reaching up to 1.8 meters in length, and are bipinnately or tripinnately compound, meaning they are divided multiple times into smaller leaflets. The leaflets are oval-shaped and have a smooth margin. Flowers: The large, bell-shaped flowers are a striking dull red or purplish-yellow color. They grow in terminal clusters and emit an unpleasant odor. They bloom at night and are pollinated by bats. Fruits (Pods): The fruits are the most iconic feature. They are long, flat, woody capsules, resembling a long, flattened sword or trumpet, and can be up to one meter long. They hang downwards from the branches, giving the tree its "Broken Bones" or "Damocles" names. Seeds: The seeds inside the pods are disc-shaped with a transparent, papery wing, enabling them to be carried away by the wind.
Healing Properties
Oroxylum indicum possesses a wide range of healing properties, primarily attributed to its anti-inflammatory, antioxidant, and astringent compounds. The root bark and stem bark are the most used parts, rich in active compounds like baicalein, chrysin, and oroxylin A. Anti-inflammatory and Antirheumatic: The bark is a potent anti-inflammatory, used to treat conditions like rheumatism, arthritis, and other inflammatory diseases. It works by inhibiting inflammatory pathways in the body. Antipyretic and Antitussive: The bark and seeds are used to reduce fever and soothe coughs and sore throats. They are often prescribed for respiratory ailments accompanied by fever and chills. Antidiarrheal and Antidysenteric: Its astringent properties make it effective in treating diarrhea and dysentery by tightening the intestinal lining and reducing fluid loss. Digestive Tonic: The herb acts as a stomachic, aiding in digestion, relieving stomachache, and improving appetite. Vulnerary: A paste made from the bark is applied externally to treat wounds and muscular pain, promoting healing. Female Tonic: In some traditions, particularly Thai, a decoction of the bark is used as a uterine tonic after childbirth to restore the body.
Advantages
The advantages of using Oroxylum indicum as a medicinal herb are numerous: Multifaceted Use: It addresses a wide range of health issues, from inflammation and fever to digestive and respiratory problems. This makes it a versatile ingredient in traditional medicine. Holistic Approach: It is often used as a tonic to strengthen the body's overall vitality rather than just treating a single symptom. Synergistic Effects: The various compounds in the plant work together to provide more potent effects than a single isolated compound. Traditional Knowledge: Its efficacy is supported by centuries of use in diverse traditional medicine systems, indicating a long history of safety and effectiveness.
Uses
Oroxylum indicum is used in various forms to treat different conditions: Internal Use: Decoction: A tea made by boiling the bark, root, or seeds in water is a common way to consume the herb. This is used for diarrhea, rheumatism, fever, cough, and as a post-natal tonic. Powder: The dried and powdered bark or seeds are taken with water or honey to treat digestive issues and sore throats. External Use: Paste: A paste made from the crushed bark is applied to the skin to relieve muscular pain, rheumatism, and wounds.

In some cultures, the unripe fruit and tender shoots are also eaten as a vegetable, valued for their bitter flavor and potential health benefits.
Using Way
The traditional preparation of Oroxylum indicum involves a few key steps: Preparation: The root bark or stem bark is the most commonly used part. It is typically harvested, cleaned, and dried. Decoction: A decoction is prepared by boiling a specific amount of the dried bark (usually 8 to 16 grams) in water until the liquid is reduced to a smaller volume. This concentrates the active compounds. Consumption: The strained liquid is consumed, often in a specific dosage recommended by a traditional practitioner. For example, it may be taken once or twice a day. External Application: For external use, the dried bark is ground into a powder and mixed with a liquid, such as water or oil, to form a paste, which is then applied to the affected area. It's important to note that while traditional use has a long history, it's always advisable to consult a healthcare professional before using any new herbal remedy, especially if you have pre-existing health conditions or are taking other medications.
