t. John’s Wort is one of the best choices to alleviate feelings of depression using herbs in the treatment of postpartum depression (but not for severe depression.) There is a lot of conflicting information in general about the safety of herbs and breastfeeding, including St. John’s Wort. From what I can find, there are no large studies on the matter. However there have been several small studies that are very supportive of St. John’s Wort during nursing.
Here is an excerpt from the article referring to the studies:
…case reports started trickling in from lactation specialists who were recommending St. John’s wort for postpartum depression and seeing positive results with no reports of any adverse effects on the nursing infant. The only study to address the issue to date was a prospective, observational cohort study with 33 breastfeeding women with depression taking St. John’s wort compared to 101 disease-matched women and 33 parity-matched health control women.1 While no statistically significant differences were reported for maternal adverse events, colic was reported in one infant in each of the latter two groups while two cases of colic, two cases of drowsiness, and one case of “lethargy” were reported in the St. John’s wort group. The symptoms were not severe and specific medical treatment was not required. No differences were reported in milk production or infant weight over the first year of life. While a small study, the current data supports the findings of an earlier pharmacokinetic study which found that the milk/plasma ratio of hyperforin was very low indicating no accumulation in the breast milk.2 These limited data points to date suggest the need for larger safety data but also suggest, with precautions, that standardized St. John’s wort extracts may prove a safe alternative to SSRIs for post-partum depression.

The amount that was used in the study was 300 mg of standardized St. John’s Wort. Most regular depression protocols for St.John’s Wort recommend 300mg three times per day. If you are considering trying St.John’s Wort here are some tips.
I think St. John’s Wort as a very important herb to alleviate the symptoms of depression and or postpartum depression, but don’t rely on it alone. It won’t restore the lost nutrients you may be needing, or any hormone imbalance issues, nor will it address any feelings of isolation or stress you may be having. Consult your physician and a lactation consultant for more information.
St. John’s Wort should not be taken if you are on prescription antidepressants, the birth control pill, or sensitive to the sun.
