Short answer: No. In Paryushan, Jains generally avoid root vegetables and root-derived spices, and ginger is considered a root. So ginger powder is not allowed in the strict Paryushan vrat.

Explanation (brief, traditional view):

• Both Digambar and Shwetambar traditions prefer to avoid kand-mool (root vegetables) during Paryushan.
• Ginger is a root-derived spice, so it is typically avoided along with other roots like potato, onion, garlic, turmeric, etc.
• Practices can vary by local sangh or guru, but the above is the common guideline for the festival.
