Which part of Belladonna is mainly used in Pharmacognosy ?
Answer: A
The part mainly used is the leaves.
Belladonna leaf (the dried leaves and flowering tops of Atropa belladonna) is the official drug. It contains the tropane alkaloids hyoscyamine and atropine, which are anticholinergic and are used as antispasmodics and to reduce secretions.
Belladonna root is also used and is in fact richer in alkaloids, which makes the root a common trap here, but the leaf is the part the standard pharmacognosy texts give as the main drug. The flowers and seeds are not the drug of commerce.
