This Elderberry Juice Is Too Good To Be True! I

This Elderberry juice is too good to be true! I was quite sick w a cold flu for the past few days ~ dizzy, very runny nose,
malise....After taking 5 teaspoons since 10 am I feel 90% better....
Told my tennis team coach there was no way I could play in a team match on Thursday
Now I feel like I can play now!
Am I taking too much?
