<unk> , also known as gamma-hexachlorocyclohexane (γ-HCH), gammaxene, Gammallin and sometimes misnamed benzene hexachloride (BHC), is an organochlorine chemical and an isomer of hexachlorocyclohexane that has been used both as an agricultural insecticide and as a pharmaceutical treatment for lice and scabies.<unk>  is a neurotoxin that interferes with GABA neurotransmitter function by interacting with the GABAA receptor-chloride channel complex at the picrotoxin binding site. In humans,<unk>  affects the nervous system, liver, and kidneys, and may well be a carcinogen. Whether<unk>  is an endocrine disruptor is unclear. The World Health Organization classifies<unk>  as "moderately hazardous", and its international trade is restricted and regulated under the Rotterdam Convention on Prior Informed Consent. In 2009, the production and agricultural use of<unk>  was banned under the Stockholm Convention on persistent organic pollutants. A specific exemption to that ban allows it to continue to be used as a second-line pharmaceutical treatment for lice and scabies.
