narcissus (Narcissus poeticus) is a fragrance. It is also used as an antispasmodic and is recommended for use in very low concentrations because its oil has been shown to impair cellular functions when added to in vitro cell cultures. In addition, large amounts of the extract may produce headaches. This general name may also include narcissus flower extract and narcissus essential wax. As a wax, it can help thicken an emulsion and is considered tonic.
