We can use our nutrients and herbal medicines therapeutically. Using specifically targeted supplements of nutrients can be helpful in overcoming many health conditions. The way it works is using them to achieve a specific therapeutic effect and for a specific period of time. Changing them as needed and required. If you have a chronic health condition you may require more of certain nutrients, which we address. The aim is always to use them to get you to a better health outcome, not to be on them forever. That is not a good practice. You can use them therapeutically, for example if you have a cold, you can use zinc which has antiviral activity, or Vitamin C to reduce histamine production and help you get over the infection faster. You then stop as you come back into optimal health.
