Ramya,
The most important foods to avoid for ulcer is all tangy and spicy foods like Tamarind, Orange,lemon, cranberry juices,raw Mango since it is sour.
And regarding greens avoid the pulicha keerai, not sure it is the tangy greens we get in Indian store.
Other than that any keerai/vegetable can be consumed.
Limit/Avoid oily diet, garam masalas, garlic and ginger.

Foods that will heal ulcer are as follows:
1. Aloe vera juice in empty stomach - ( take the flesh out of Aloe vera and grind in blender and drink) works wonders
2. White pumpkin juice - cut white pumpkins and grind in belnder and filter in muslin cloth.
Always remember to eat on time in small quantities every two/three hours. Dont leave the stomach empty which will secrete acid and will increase ulcer.
Ulcer is curable if proper diet restrictions are followed in very short span. Above all it is important for ulcer patients not to take things seriously and feel for something, since it affects the acid secretion. Stay cool mentally.
Hope this helps.

Ramya,you can take methi leaves(vendaya keerai),banana and almond milk.Boil 2 tbspn of methi leaves in 1 cup of water for 2-3 minutes,strain and drink it in empty stomach.This will definetly help.Also dry roast and powder almonds and boil it in milk,have it once daily before eating dinner or before going to bed.Banana is highly benefieciary for reducing ulcer.

Ramya, I don know about the greens recommended for Ulcer patients. But, Taking carrot juice regularly in morning, will be helpful to cure ulcer.My aunt is doing this and she is ok now. You can atleast reduce the ulcer. Hope it helps. Take care.
