Colostrum milk - Most important benefits: Helps build immunity

Caution: Excess colostrum milk is bad - may cause in-digestion, and loose motions. (http://www.gayatrivantillu.com/recipes-2/sweets-and-savory/junnu)

Important: Prepare it with Jaggery, Cardamom and Pepper

Pepper - is used to bring down vata dosha (http://indianhealthyrecipes.com/junnu-kharvas-recipe/)
Jaggery - is used for digestion
Cardamom - is used for digestion

Firstly, the calf can't drink the entire milk yielded by its mother, secondly even if it drinks the entire quantity of milk, it suffers from in-digestion and loose motions and can die too. Good & seasoned farmers are careful to allow the calf to drink only what is needed.

Therefore Colostrum milk too is given to the calf only in desirable quantity. This milk has a lot of essential items needed by the calf to survive. Excess colostrum milk though extracted is either  consumed or discarded. It can't be left in the udder because it would make the udder swell & become painful

My comment: Colostrum milk is Perhaps, that's why jaggery and cardamom are added for easy digestion.

Negatives

Colostrum has actually been found to increase Prostate Cancer in Men.

After three weeks of taking the recommended dose, I was sensing that it was influencing my hormone levels. I went to my doctor to get a blood draw, and sure enough, my estrogen levels had risen to 4.5 times their normal level. I am a 57 year old woman, and I've been measuring my hormone levels at least once a year for the last 18 years. I was shocked and stopped ingesting this product for one week. Another blood draw after a week of stopping showed that my estrogen levels were back to normal.
