No - nothing cures a cold in 24 hours; over 200 viruses cause them, there is no antiviral, and most run 7 to 10 days.
What you can change is how bad the next day feels. Real rest is the closest thing to a treatment - sleep is when immune response does its work - plus fluids, honey for cough (over age one), saline rinses, and acetaminophen or ibuprofen for aches. Zinc lozenges started within 24 hours of symptoms have some evidence for shortening the course by about a day, though results are mixed. Vitamin C after symptoms start, antibiotics, and pushing through do not work. A cold not improving by day 10 - or improving then slamming back worse - deserves a visit.

What to do
Common questions
Can you get rid of a cold in 24 hours?
Honestly, no - nothing cures a cold in 24 hours. More than 200 viruses cause colds, there is no antiviral for them, and antibiotics do not touch them; most colds run 7 to 10 days from first sniffle to clear. But you can genuinely change how the next 24 hours feel and possibly shave the total course. What actually helps: rest - real rest, not pushing through - because sleep is when immune response works hardest; fluids to thin mucus; honey for the cough (adults and kids over one); saline rinses for congestion; and acetaminophen or ibuprofen for aches. Zinc lozenges, started within 24 hours of symptoms, have some evidence for shortening colds by a day or so, though study results are mixed. What does not work: vitamin C megadoses after symptoms start, antibiotics, and powering through. If a cold is not improving by day 10, or improves then slams back worse, that is a different problem worth a visit.
