Is it permissible to sell a health product without being certain of its positive effect on the majority of users, and is there any mention in the Sunnah regarding other bee products such as royal jelly, pollen, beeswax, and bee venom, similar to what is mentioned concerning honey?

Selling a medicinal drug requires adherence to regulatory procedures, proof of its efficacy through laboratory tests, and compliance with the conditions set by international health organizations and ministries of health, for the benefit of people. Random experimentation is not sufficient, for a Muslim perfects what he manufactures. Allah the Almighty says: (O YOU WHO HAVE BELIEVED, DO NOT BETRAY ALLAH AND THE MESSENGER OR BETRAY YOUR TRUSTS WHILE YOU KNOW) Al-Anfal/27. And the Prophet, peace and blessings be upon him, said: (Indeed, Allah loves that when one of you does a job, he does it proficiently). As for royal jelly, beeswax, and pollen, there is nothing in the Prophet's Sunnah that indicates specific benefits for them.
