Bitter Gourd (Karela) Purity Audit

Bitter gourds are high-risk vegetables frequently dyed with Malachite Green to look vibrant and fresh, or injected with Oxytocin to double their size overnight.

1. The Cotton Rub Test: 
Rub a wet cotton ball on the skin of the karela. If the cotton picks up a green tint, it is coated with Malachite Green, a toxic industrial dye.

2. The Stem Inspection: 
Look closely at the stem-end. If you see tiny, dark pin-prick marks, it indicates an injection site for Oxytocin growth hormone.

3. The Water Bleed: 
Soak the karela in warm water for 10 minutes. If the vegetable turns the water green, it is artificially colored.

4. Internal Texture: 
Cut the karela open. A naturally grown one is firm and has a natural seedy core. If the center feels unusually "spongy" or "puffy" while the exterior is large, it indicates forced chemical growth.

Quick Safety Tips

Perform the cotton rub test for green dye
Check the stem for injection marks (Oxytocin)
Select medium-sized gourds - avoid unnaturally large ones
Soak in salt water to help remove surface chemicals
