Medicine Switches Bacteria On, and It Also Fixes the Neighbourhood They Live In

The medicine that does not press the brake for you — following magnolia bark down to its ingredients

People come after being told their breathing feels tight but the tests are normal. The lung is an organ; breathing is regulation. Tests look at the organ. The ingredients of magnolia bark do not manufacture a brake that isn't there — they help the brake the body already has work better.

May I Take Herbal Medicine While Pregnant or Breastfeeding?

In the body during this period there are two people. Both "no herbal medicine during pregnancy" and "herbal medicine is natural, so it is fine" are wrong. There are materials that cannot be used, materials used with caution, and cases where they are used when needed.

The Claim That Herbal Medicine Has Not Been Scientifically Proven

The claim that 'herbal medicine has not been proven' contains both a correct part and a mistaken part. Having no research and having been researched and shown to have no effect are completely different things.

Unused Tissue Withers — But Filling It Back In Does Not Bring It Back to Life

Tissue long unused withers. But pushing good things in does not bring it back to life. Atrophied tissue has also lost the strength to handle it. Before deciding what more to add, I first look at what this body can bear.
