Dear Sampada Farms
Licorice (or Sweet root) is very popular in foreign countries and very common produce there. Many companies made several products using them and check for "licorice candy".. Excess use of licorice is harmful to one's liver. Just treat it as an agent replacement of sugar. Please "google" to check out its market potency. May be in India, there might be some market... or may have chance to market in Asian countries only (because of its limited produce comparing to European and US countries). If you want to cultivate, the better way is to market independently by producing any by-products of it.
Regarding Spam Mails:
The best idea is don't make any swift contacts with unknown/unheard companies outside the country who always send replies that they've your requirement in bulk quantities. It is very tough task to establish business relationship with outside countries. Lot of issues to get export/import permits. After all, money transaction is major among all. Without knowing a company or their reputation, how can one deal online and send money blindly? (if you want to import some material).
Most of the scams are running with .co.uk and .fr or other country webmails. London/China/Hong Kong/Nigeria or other African Countries are main sources of such scams. So be careful and aware of the postings, their posting origins and email and contact phone numbers they are asking....
With little knowledge, one can easily identify spam/scam postings.
Thanks and regards...
