I lost my taste and smell on chol hamoed sukkos. While I was sick I was taking zinc, vitamin c and quercitin.
I continued to take zinc a couple times a week and figured my smell would eventually come back. Taste came back like a week after sukkos but couldn't smell anything unless I put my face into it. I couldn't smell anything cooking, frying, burning, diapers, cleansers, etc.
I saw an instagram post from rabbishlomofarhi where he said that he took boswellia pills for 7 days and he got his smell back. I figured there is nothing to loose so I ordered them and started to take them like 2-3 days before Chanukah. Took 2-3 per day and by day 6 I started to smell! First day of Chanukah I couldn't smell any latkes frying but by the last day I walked into the house and I smelled exactly what was cooking! The day I started smelling felt so good! Was enjoying my co-workers grilled cheese smell and the others tuna smell..
I used the pill from the attached link

Still trying to take it everyday but BH my smell is back, not sure if it's as strong as before but i am definitely aware of the smells around me.
Eta: instagram post that prompted me to buy it.
