Eat it or tea.....
What a choice..... It is pretty "spicy" stuff.
Well, considering the idea that it isnt fresh..... I would go tea.... make a THICK tea..... maybe 40+ grams, ground and boiled/simmered ( dunno if heat is going to effect it or not ) for 30 minutes. maybe try to keep it to 8oz of water..... 4 for you 4 for him...... and a good chaser.... sample diff stuff out..... take a LITTLE sip. chase it..... I am not sure much is going to help, get as much down as you can.......
And if it comes back up..... or you cant get it ALL down..... you used 20 grams each. So if your going to get something..... it should work.
