General Uses Top
Suggest a correction!Common products:
- Wood for small timber and carpentry; also used for pulp. Heartwood pale brown; wood described as moderately heavy, fine to medium textured, with interlocked grain. Logs and sawn timber marketed locally; pulp rated moderate with satisfactory burst strength and high tear strength.
- Pulp and paper: suitable for kraft pulping; moderate yield; moderate Kappa number; pulp properties: burst index 5.2–6.5 kPa·m²/g, tensile index 70–78 kN·m/kg, tear index 10–12 mN·m²/g, brightness 24–29% ISO; acceptable drainage and brightness for writing/printing and packaging grades.
Industrial and craft applications:
- Fiber and pulp: bast fiber recognized (together with many Acanthaceae) as an alternative source of pulp fiber in some developing regions; fiber suitable for short-fiber paper grades and cardboard.
Wood and fiber:
- Bark: includes phloem and bast fibers; produces a gum/resin (dravid root) used as a substitute for true dammar; a valued varnish and lacquer ingredient; gum described as hard, clear, and odorless when dry, soluble in turpentine and aromatic hydrocarbons; no nicotine detected; yield around 0.3%.
- Wood density: 0.73–0.78 g/cm³ at 12% moisture; basic density 0.65 g/cm³.
Colorants and tanning:
- Bark tannins: contain ellagitannins (including chebulagic and chebulinic acids) and gallic acid; widely used for tanning leather in India, as a direct and sometimes mordant-free dye, particularly for wool and silk; yields deep brown to reddish-brown shades.
Properties relevant to use:
- Wood strength and stability: suitable for carpentry and joinery; pulp strengths reported for kraft process. The tanin composition and gallic acid content correlate with leather tanning and dye performance.
Standards and regulation:
- India: Gum accepted as a recognized dammar substitute; marketing and sale governed by national standards and common practice. Pulp conforms to industry conventions (e.g., pulp brightness and strength measured by ISO/ASTM methods).
Sustainability and sourcing:
- Supply reportedly relies on wild harvesting; small-scale forest management in India prioritizes sustainable extraction to reduce bark damage and maintain stock.
