Camphor should not be applied to the nostrils of infants even in small quantities, as this may cause immediate collapse.

The UK Committee on the Review of Medicines recommended that camphor should not be included in products intended for the treatment of hepatic and biliary disorders, gallstones, colic, renal disorders, urinary tract infections, or ureteral stones. The use of camphor parenterally or as irrigants was considered undesirable due to the associated safety hazard.

...The literature from 1964-1983 /was reviewed/, and... the mean dose ingested by patients with major symptoms /was/ 124 mg/kg, with the mean dose in fatal cases being 199 mg/kg. /It was/... suggested, based on /the/ analysis of these figures, that patients ingesting <10 mg/kg of camphor and displaying no symptoms required no treatment. Adults have survived ingestions of up to 42 g, but usually doses in excess of 2 g produce dangerous effects. Fatal doses in children have ranged from 0.7-1.0 g.

In the liver microsomes of female mice, two induction phases during inhalation of DL-camphor were found. During the first 24 hr the apparent molar activity of the ethylumbelliferone dealkylase decreased. In the second phase, the molar ethylumbelliferone dealkylase activity was constant.

Camphor is rapidly oxidized to campherols (2-hydroxycamphor and 3-hydroxycamphor), and then conjugated in the liver to the glucuronide form. Camphor-related metabolites are relatively fat-soluble and may accumulate in fatty tissue.

167 minutes (200 mg camphor ingested alone); 93 minutes (200 mg camphor ingested with a solvent - Tween 80).
National Poisons Information Service Center, United Kingdom; Poisons Information Monograph: Camphor. (March 1996). Available from, as of June 30, 2014: https://www.inchem.org/documents/ukpids/ukpids/ukpid19.htm
Camphor is a naturally occurring compound that is used as a major active ingredient of balms and liniments supplied as topical analgesics. ... Capsaicin and menthol, two other topically applied agents widely used for similar purposes, are known to excite and desensitize sensory nerves by acting on two members of transient receptor potential (TRP) channel superfamily: heat-sensitive TRP vanilloid subtype 1 (TRPV1) and cold-sensitive TRP channel M8, respectively. Camphor has recently been shown to activate TRPV3, and here /investigators/ show that camphor also activates heterologously expressed TRPV1, requiring higher concentrations than capsaicin. Activation was enhanced by phospholipase C-coupled receptor stimulation mimicking inflamed conditions. Similar camphor-activated TRPV1-like currents were observed in isolated rat DRG neurons and were strongly potentiated after activation of protein kinase C with phorbol-12-myristate-13-acetate. Camphor activation of rat TRPV1 was mediated by distinct channel regions from capsaicin, as indicated by camphor activation in the presence of the competitive inhibitor capsazepine and in a capsaicin-insensitive point mutant. Camphor did not activate the capsaicin-insensitive chicken TRPV1. TRPV1 desensitization is believed to contribute to the analgesic actions of capsaicin. /The authors/ found that, although camphor activates TRPV1 less effectively, camphor application desensitized TRPV1 more rapidly and completely than capsaicin. Conversely, TRPV3 current sensitized after repeated camphor applications, which is inconsistent with the analgesic role of camphor. /Investigators/ also found that camphor inhibited several other related TRP channels, including ankyrin-repeat TRP 1 (TRPA1). The camphor-induced desensitization of TRPV1 and block of TRPA1 may underlie the analgesic effects of camphor.
