Great for insomnia around 3-4am and over indulgence - work/food/alcohol!
It's often called the 'hangover remedy' as it relieves the symptoms of high living and mental stimulation, but may also be helpful for headaches, indigestion, asthma and crampy pains when the picture fits.
Both potency's are great!
6C covers a more wide range of symptoms so its a good choice if you're not sure it's the best remedy for your symptoms. It's also more gentle on the body and if you're quite sensitive energetically then your immune system isn’t going to need too much stimulation to get that natural healing action happening.
30c potency is a good mid-range potency – it works on all levels. It's great to use this potency if we know that the symptom match the remedy picture well.
