Star Jasmine (Trachelospermum jasminoides) is a highly fragrant, evergreen climbing vine popular in many gardens. It is also known as Confederate Jasmine or Chinese Star Jasmine. Star Jasmine is generally considered non-toxic to both humans and common domestic animals, posing a low poisoning risk.
Official Toxicity Status
Authoritative organizations like the American Society for the Prevention of Cruelty to Animals (ASPCA) classify Trachelospermum jasminoides as non-toxic to dogs, cats, and horses. This means the plant does not contain harmful compounds that cause systemic poisoning. However, consuming any non-food plant material, including the leaves, flowers, or stems, may still result in mild, temporary stomach upset.
These minor gastrointestinal symptoms, such as vomiting or diarrhea, are typically a reaction to the plant fiber rather than any chemical toxin. The plant produces a milky sap when broken, which can act as a mild irritant. This sap potentially causes contact dermatitis or eye irritation upon direct contact. While the overall safety profile is low-risk, it is advisable to prevent pets or small children from ingesting large quantities.
Differentiation from Toxic Look-Alikes
The most significant concern regarding Star Jasmine is its frequent confusion with the highly toxic Carolina Jasmine, or Yellow Jessamine (Gelsemium sempervirens). Carolina Jasmine is dangerous, containing poisonous indole alkaloids such as gelsemine, which can be fatal if ingested by humans or pets. Although the names are similar, the plants belong to different genera and families.
To distinguish the two, one must look closely at the blooms. Star Jasmine produces white, pinwheel-shaped flowers with five petals. In contrast, the toxic Carolina Jasmine features bright yellow, trumpet-shaped flowers. Recognizing these distinct visual characteristics is important for plant safety.
Managing Minor Exposure Incidents
If a person or pet has minor exposure, such as skin contact with the milky sap, the affected area should be rinsed thoroughly with soap and water. For cases of mild ingestion, such as a pet nibbling a few leaves, the recommended action is to simply monitor for signs of stomach upset, like drooling or a single episode of vomiting. These mild symptoms typically resolve on their own without intervention.
If a larger quantity of the plant has been consumed, or if symptoms are severe, persistent, or worsen, professional help should be sought immediately. For humans, contact a regional Poison Control Center, and for pets, a veterinarian or the ASPCA Animal Poison Control Center can provide guidance. When reporting an incident, it is crucial to specify the plant as Trachelospermum jasminoides to confirm its low-toxicity status and avoid confusion with toxic look-alikes.
