Answer by Dr. Ru: About Caswell No. 158 usage in lactation

Caswell No. 158 is an oleoresin contained in ripe and dry fruits of hot peppers. It is used for seasoning food and as medicine for topical analgesia in the form of creams, gels or patches. A low absorption into plasma (very low levels or undetectable in plasma) and rapid clearance make it highly unlikely the passage of significant amount toward breast milk. Do not apply on the chest or thoroughly clean it off before breastfeeding.
