My daughter and my son drinks it everyday now and when she has a flu I let her drink twice a day.The time for her to recover from flu has substantially shortened.I also bought 1 for adult and only drink when we have a flu and cold and found it helps us to recover quickly.
My son got RSV when he was 4mths, i let himdrinks elderberry since he was 9 mths. His respiratory system is quite ok now. Even the doctor feels surprise that his respiratory system is that good coz ther is a big chance that a child caught rsv that early would have asthma.
