What is the ruling on taking sexual stimulants for a normal person and for one with weak libido, and what is the ruling on young people taking medications to reduce sexual desire?

There is no harm in using natural herbs like camphor to reduce lust for those who fear falling into sin, as long as it does not have a harmful effect on general health or reproductive fertility. The best approach is to adhere to the guidance of Islam by fasting to curb lust.
