Yes, Jains can eat aliv seeds (also called halim seeds / garden cress), from the point of view of Jain food rules.

From Jain dharma perspective:

• They are plant-based seeds, not from underground like potato, onion, garlic, etc., so there is no problem like “kand-mool” here.
• They are not living insects or micro‑organisms themselves (like curd full of bacteria issue), so there is no special prohibition.
• They are generally treated like other edible seeds (til, saunf, methi, etc.).

Only take care of these points, as a conscientious Jain:

1. Cleanliness / insects

- Check and clean properly so there are no small stones, insects, or worms mixed with the seeds.

1. Saattvik preparation

- Prepare them without eggs, meat, fish, alcohol, or other non‑Jain items. - Avoid eating them at night if they are in a wet, cooked, or mixed form that may easily attract micro‑organisms (follow your usual family/sampradāy rules about night‑eating).

1. Health side (not religious, but practical)

- Aliv is considered “hot” (uṣṇa) in nature. Take in moderation, especially in pregnancy or if you have any medical issue—better to follow your doctor and family’s practice.

So, as per Jain dharma, aliv seeds are permitted, with the normal Jain care for ahimsā, cleanliness, and simplicity in food.
