Dosage of fresh v dried v powdered extract of herbs?

[Guest guest]

Hi All,

 

My notes on dosage of Chinese herbs suggest that:

 

1. FRESH herbs are dosed at 2-3X the dose of the DRIED herbs;

 

2. Depending on the ratio of DRIED HERB : DRIED EXTRACT,

dried herbal EXTRACTS are dosed at 10-50% of the dose of the

DRIED HERB.

 

Calculated from adult human dosage data in my notes on single

TCM herbs, the mean doses of 16 fresh (crude, undried), 512 dried

and 87 dried extracts (powders, pills, tablets) were, respectively,

circa:

 

FRESH herb: 40g/d;

DRIED herb: 13g/d;

Herb EXTRACT: 5g/d.

 

However, depending on the herb (and its safety/toxicity), there was

huge variation around these mean values.

 

Would experts care to comment on these figures?

 

 

 

 

 

Best regards,
