some one once advised me to put lavender in it (mistake, its calming, but it turned out she had PMS and the lavender made it worse- apparently lavender can cause female hormones to increase in number, which was a mistake)
cinnamon sounds nice :)
theres a herb directory like article, its several by name alphabeticaly, just hit the article tab :)

what confuses me is why you have made one for your husband... i understand making one for someone you arent as close to, but i advise trying a non magickal way always, but especially for close relationships, but thats my opinion
