Oregano for colds

Hello po is it okay to take oregano juice in small amount lang naman. Runny nose po kasi aq ang dami ko kasi puyat the whole week last week, umuwi kasi aq ng province and sobrang init samin tapos lage walang power then pagbalik ko dito ang lakas ng aircon namin, so a lot of puyat then nanibago ung katawan ko from sobrang init to sobrang lamig. Alam mo naman sa panahon ngaun kahit sipon lang kapag ngpacheckup ka kinoconsider na nila na covid. And you have to undergo with a lot of test that will cost you so much. Sa ngaun ngtake aq ng oregano with kalamansi mga 2tablespoon lang naman. Antibacterial and anti fungal kasi ang oregano, been using this since my childhood days since probinsyana aq e😁and it so effective sakin. But im not sure during pregnancy ko kung safe. Thank you in advance.
