No worries, I was not thinking of this tea for my dad.
Leo, thank you for the careful and comprehensive response to my question. I am very grateful.
My 80-year old father suffers from the following conditions:
*anger issues and anxiety
*chronic renal (kidney) deficiency caused by decades of excess alcohol and steroidal medications
*poor cardiac function
*muscle tension
*sleeplessness
*low energy
*high blood pressure
And I could continue:(
Not my question. But thanks anyway:)
