truffles could be an aphrodisiac, anti-depressant and sterol source:
For centuries, truffles have been believed to possess mystical aphrodisiac powers. Food connoisseurs describe the scent of truffles as sensual and seductive. A survey has reported that, about 95% of the non-Bahraini respondents and 72% of the Bahraini respondents eat truffles for sexual reasons. 5á-Androst-16-en-3-á-ol (androstenol), a steroidal compound belonging to the group of musk odorous 16-androstenes, recognized as a pheromone that could increase the sexual arousal of human female, adjust moods as submissive rather than aggressive in female menstrual cycle and antagonize anxiety and convulsion by positively modulating the GABA receptors. Due to its pleasant odour and pharmaceutical function, androstenol has been developed to perfume with high value in market.
Also, it has potential in drug development for anti-depression. From the fruiting bodies of T. indicum, a new polyhydroxy sterol glycoside named tuberoside has been isolated along with four known ergostanes. These compounds are assumed as structural constituents of cellular biomembranes and precursors of steroid hormones.
