In Jain Dharma, the general rule is:

• All underground/root vegetables (kand-mool) are to be avoided because:

- They contain countless living beings (one-sensed jivas). - When uprooted, the entire plant is destroyed, causing more himsa (violence).

Ginger is a root, like potato, onion, garlic, carrot, etc. So, according to strict Jain principles, you should not eat ginger.

In practice:

• Many sincere/strict Jains (both Digambar and Shwetambar) avoid ginger completely.
• Some household traditions are a bit lenient, but from the point of view of ahimsa and vows, avoiding ginger is the safer and more dharmic choice.

If you want to follow Jain food rules properly, it is best not to eat ginger.
