Basically, the placenta is either steamed before dehydrating (Steamed preparation) or it is dehydrated from raw (Simple preparation). The Steamed preparation is loosely based on Traditional Chinese Medicine (TCM) principles, with lemon (grounding), ginger (circulation) and chilli (warming) in the steaming water.
Feedback from mothers is directly comparable for both preparations, so whichever you choose, you end up with very potent capsules.
On a practical level, the Simple preparation tends to yield 10-15% more capsules than Steamed and the majority of new mothers opt for this preparation.
