Plants of the genus Cannabis have been gaining attention in medicine. The most outstanding treatments include antispasmodic, analgesic, antiemetic, neuroprotective and anti-inflammatory actions. The aim of the study was to describe patents associated with cannabis and cannabinoids as a treatment for pregnant women. A search was carried out on four patent bases: National Institute of Industrial Property, Latipat, Espacenet and Patentscope. The used search keys were “Cannabis”, “Cannabidiol”, “Cannabinoids”, “CBD” and “THC” associated with “pregnant women”. Patents in any language and year were considered. A total of 1,402 patents were found in all the used databases. After reading the title and abstract, patents were excluded if they did not meet the eligibility criteria and/or if they were duplicates, thus leaving 11 patents on the use of cannabis and/or cannabinoids as treatment in pregnant women. A critical analysis was carried out. All selected patents were from the Asian continent (China), focusing on traditional Chinese medicine for treating various possible changes during pregnancy and also for diseases prevention in the postpartum period. It was found that the main causes for the need of such treatments were related to spleen deficiencies, inability and/or moisture stagnation. Finally, the vast majority of treatments used Cannabis fruits associated with other plants. Given the above, patents related to cannabis and cannabinoids for the treatment of pregnant women in the peri and postnatal periods were found to be associated with traditional Chinese medicine.
