Chronic or persistent complaints, which may or may not be mentioned above, require a different treatment and dosage protocol so are best managed by a qualified homeopath for good results.

Dosage Instructions (suitable for babies to adults)

For acute and self-limiting complaints, take one pill or five drops of the remedy every 1 to 4 hours (1 hour for intense symptoms, 4 hours for milder ones). Once an improvement is noticed, stop dosing and repeat the remedy only if symptoms return. If there is no improvement at all by three doses, choose a different remedy or seek professional guidance.
