Is it true that the more doses of antibiotics used in pigs, the better the effect?

No, you need to use an appropriate dose according to the condition. If the dosage is large and exceeds the conventional dosage, the side effects will be even greater.

Your statement is not very scientific:

1) Antibiotics are against germs (bacteria) and have no direct effect on viruses.

2) Isatis indigotica does not exist in ancient books. Isatis indigotica in Compendium of Materia Medica in the Ming Dynasty was only used as a guide for folk prescription and Isatis indigotica, not the root of Isatis indigotica now.

3) Radix Isatidis is an effective drug discovered by Ye et al. in the Qing Dynasty after the failure of traditional Chinese medicine to treat plague, which is a viral explosive infectious disease. Simply put, the use of Radix Isatidis has a history of about 200 years at most, not 2000.

The existence of Radix Isatidis today is not accidental, nor is it developed from traditional Chinese medicine theory, but new traditional chinese medicine theory is the product of practice.
