The name Portulaca dates back to Pliny the Elder (AD 23-79), who first referred to purslane using this Latin term. The name alludes to the plant’s purging properties, which were recognized in early medicine.
Evolution of the English Name
- In 1387, purslane was recorded as “purcelan” in a 14th-century manuscript from Pembroke College, Oxford.
- Over time, it took different spellings such as purcelane, purselaine, and pesseline.
- The modern spelling “purslane” was standardized by Asa Gray in 1857 in his First Lessons in Botany.
Taxonomic Classification
- Carl Linnaeus (1753) officially described the genus Portulaca in his work Species Plantarum.
- Antoine Laurent de Jussieu (1789) classified the Portulacaceae family.
- The species name oleracea is derived from Latin, meaning “suitable for food or cultivation”.

Safety of Purslane for Humans and Animals
Purslane (Portulaca oleracea) is a non-toxic and highly nutritious plant that is safe for human consumption, including infants and children. It is widely consumed in many cultures and has no recorded cases of toxicity in humans. However, while purslane is safe for people, it contains soluble calcium oxalates, which can be harmful to animals, particularly pets and livestock.
Human Safety and Benefits
- Purslane’s leaves, stems, and flowers are completely edible and rich in vitamins, minerals, and omega-3 fatty acids.
- It is regularly included in traditional dishes, salads, and stews around the world.
- Scientific studies confirm that purslane does not pose any health risks to humans, including toddlers and infants.
Risks for Animals
- Unlike humans, certain animals (dogs, cats, and livestock) cannot process calcium oxalates efficiently, leading to potential toxicity if consumed in large amounts.
- In animals, ingestion may cause symptoms like vomiting, tremors, or kidney issues.
- Pet owners should keep purslane out of reach to prevent accidental ingestion.
Key Takeaway
Purslane is a safe and beneficial plant for humans but can be toxic to animals due to its calcium oxalate content. While people can enjoy its nutritional value, pet owners and farmers should exercise caution to protect their animals from potential harm.
