Loose Motion or Diarrhea

Ayurveda does not suggest using any medicine initially to stop loose stools. Therefore, Shankha Bhasma should be used when patient has passed at least six stools or in moderate to severe diarrhea. Shankha Bhasma works well when patient has frequent stools with small amount of stool, severe abdominal cramps and abdominal gas.

Indigestion, Heartburn, GERD

Shankh Bhasma is a good acid neutralizer, which helps reducing hyperacidity in the stomach and may rectify the acid production.

In addition to neutralizing acid in the stomach, it also eliminates AMA toxins, which may also be associated with heartburn or indigestion.

Shankha Bhasma is more effective when patient has abdominal distension, heaviness in the abdomen, gas, nausea with feeling of eaten food or sour and burning sensation in the throat or mouth.

Abdominal Cramps or Pain

Shankha Bhasma has potent antispasmodic action on abdominal muscles. It reduces abdominal cramps, which may occur due to either diarrhea or any other underlying cause. However, Shankh bhasma works well with Praval pishti and Sootshekhar Ras in spasmodic dysmenorrhea.

Minimum Effective Dosage 10 to 30 mg in infants, 60 mg in children & 125 mg in adults *
Moderate dosage (Adults) 125 mg to 500 mg *

Side Effects

Shankh Bhasma can cause fissure (fine cracks or cuts) on tongue when kept on tongue without mixing it with honey or any other remedy. Secondly, it may also cause constipation in some patients when it is used alone.

Therefore, adjuvant is very important for using shankha bhasma. The most appropriate adjuvants and combinations should be used for getting more benefits and preventing side effects.
