Clove oil is full of eugenol.
Clove oil is used in toothache analgesics like Anbesol. I think it helps numb tissues.

Abstract;Potential activity of herbal extracts on sebum secretion was studied. Among the herbal extracts tested, polyol-soluble licorice extract P-U (product name) derived from Glycyrrhiza inflata showed the most potent testosterone 5 .ALPHA.-reductase inhibition, androgen receptor binding inhibition and antimicrobial activities, which are closely related to sebum secretion. In addition to the findings on polyol-soluble licorice extract P-U, clove extract and peppermint extract showed testosterone 5 .ALPHA.-reductase inhibition, arnica extract and rose fruit extract showed androgen receptor binding inhibition, alpinia speciosa root extract and scutellaria root extract showed estrogen receptor agonists, and sophora root extract showed antimicrobial activity.

Abstract
Sensory neurons release calcitonin gene-related peptide (CGRP) on activation. We recently reported that topical application of capsaicin increases facial skin elasticity and promotes hair growth by increasing dermal insulin-like growth factor-I (IGF-I) production through activation of sensory neurons in mice and humans. Raspberry ketone (RK), a major aromatic compound contained in red raspberries (Rubus idaeus), has a structure similar to that of capsaicin. Thus, it is possible that RK activates sensory neurons, thereby increasing skin elasticity and promoting hair growth by increasing dermal IGF-I production. In the present study, we examined this possibility in mice and humans. RK, at concentrations higher than 1 μM, significantly increased CGRP release from dorsal root ganglion neurons (DRG) isolated from wild-type (WT) mice and this increase was completely reversed by capsazepine, an inhibitor of vanilloid receptor-1 activation. Topical application of 0.01% RK increased dermal IGF-I levels at 30 min after application in WT mice, but not in CGRP-knockout mice. Topical application of 0.01% RK increased immunohistochemical expression of IGF-I at dermal papillae in hair follicles and promoted hair re-growth in WT mice at 4 weeks after the application. When applied topically to the scalp and facial skin, 0.01% RK promoted hair growth in 50.0% of humans with alopecia (n = 10) at 5 months after application and increased cheek skin elasticity at 2 weeks after application in 5 females (p < 0.04). These observations strongly suggest that RK might increase dermal IGF-I production through sensory neuron activation, thereby promoting hair growth and increasing skin elasticity.
