Hi Alex,
Thank you for the info.  I believe because the properties of thinning of the 
blood may account for the help with the eyes. From Linda Rector-Page
secondary uses:  as nutritive and strengthener for the blood.  as part of a 
blood balancing  formula that can  help ringing in the ears, heart 
palpitations, and blurred vision....
Have you had success growing donq quai.  I grew Sun Flower seeds for the 
first time and did quite well.  I agree if I can grow it I would prefer
to that way I would know the purity.  Any tips I would appreciate.
