Storing your placenta capsules adequately as instructed and avoiding taking them during any time of active infection (as per the TCM principles) will reduce your chances of experiencing any side-effects.
Very rarely have any side-effects been reported directly to myself from over the 8+ years I’ve been providing this service. This includes the women who also complete the feedback form at the 6 weeks postnatal follow up.
A few new mothers reported mild headaches and suspected it was the capsules. This was easily remedied by reducing their dosage. Another woman found she also had to avoid taking her capsules in the afternoon as they gave her so much energy she found it hard to fall asleep!
