"Gas ki fakki churan" is traditionally translated to "Ayurvedic powder for gas relief" or "Digestive powder for acidity and bloating" in English. It is typically a mixture of herbs and salts meant to be swallowed directly (followed by water) to quickly relieve digestive issues.

Common ingredients found in these formulas include:

• Ajwain (Carom seeds)
• Kala Namak (Black salt)
• Jeera (Cumin)
• Amla (Indian gooseberry)
• Sonth (Dry ginger)

If you are looking to buy or search for these, you can look up terms like Gas relief churan, Digestive powder, or Ayurvedic antacid powder.
