Is there a difference between the strength and lightness of the medicinal foam

The concentration of the medication can affect its efficacy and safety, and usually needs to be adjusted according to medical advice. Excessive concentration may increase the risk of adverse reactions, while insufficient concentration may decrease the efficacy. When the concentration of the drug solution is high, the content of effective ingredients per unit volume is higher, which may act on the lesion site faster. But some medicinal herbs contain irritating ingredients, and high concentrations can easily cause gastrointestinal discomfort or skin allergies. For example, excessive concentration of medicinal liquor for external use can cause skin burns, while excessive concentration of medicinal soup for internal use may damage the gastrointestinal mucosa. If the boiling time of traditional Chinese medicine is deliberately prolonged to make the medicine more concentrated, it may actually damage certain volatile components. When the concentration of the drug is low, the safety is relatively high, making it suitable for people with weak constitutions or those who are taking it for the first time. But it is necessary to extend the medication cycle in order to achieve the expected effect, for example, if the medicinal herbs used in tea replacement drinks are repeatedly brewed multiple times and the effectiveness is analyzed to be insufficient. Some acute symptoms that require rapid onset of action, such as the use of antipyretic drugs for external wind and cold, may result in insufficient sweating and antipyretic strength when the concentration is insufficient.

It is recommended to strictly follow the doctor's advice or drug instructions to control the concentration, use standard measuring instruments for decoction of traditional Chinese medicine, and test skin tolerance for topical drugs. During the medication period, observe the body's reactions. If any discomfort such as dizziness or rash occurs, stop using the medication in a timely manner and consult a physician. Daily storage of medicinal materials should be sealed and moisture-proof to avoid the loss of effective ingredients that may lead to a decrease in actual concentration.
