Kalmegh Powder, also known as Kalmegh, Kalamegha, Bhuminimba and King of Bitters, is a traditional botanical powder associated with Andrographis paniculata (Burm.f.) Nees, a small annual herb belonging to the Acanthaceae family.

The plant is widely recognized by its characteristic intensely bitter taste, which is reflected in the common English name King of Bitters.

• Plant part
• Drying conditions
• Grinding
• Storage

aroma.

The aroma can vary with freshness, drying and storage.

Natural Taste

Physical Testing

• Appearance
• Colour
• Moisture
• Particle size
• Foreign matter
• Odour

Botanical Testing

• Species identification

• Powder microscopy

Chemical Testing

Where appropriate:

• Ash values
• Extractive values
• Chromatographic fingerprint
• Andrographolide or other appropriate marker analysis

Safety Testing

Depending on applicable requirements:

• Microbial limits
