No, one cup of hot tea or a tincture in hot water will usually do it.
For high fevers you use Febrifuges or cool baths.
Fever management is important, fevers inhibit viral replication, I do not lower fevers until the person feels hot and has a temperature over 101.5- 102, the more difficult situation in young children who spike really high fevers - see the pediatrician and people who have fevers over 102 and still feel cold, whioh means the body wants the fever to go higher to a more dangerous level.
I do not treat low grade fevers, just manage symptoms and discomfort.
