Caution🐾Sansevieria · (Dracaena trifasciata)
Asparagus family (Asparagaceae)
Description
With its stiff, upright, yellow-and-green banded leaves, the snake plant is one of the toughest and easiest houseplants to keep, grown year-round purely for decoration. Botanically part of the asparagus family, its tear-resistant leaf fibres, made largely of cellulose, were traditionally worked into cord and woven textiles in its native African range. The leaves also contain steroidal saponins, organic acids and flavonoids, and the plant is popularly regarded as an air-freshening houseplant. Ordinary handling poses no risk to people, though the sap can mildly irritate sensitive skin. For dogs and cats, however, the saponins are toxic and can cause vomiting, diarrhoea and excessive drooling if eaten — the plant should therefore be kept out of pets' reach.
When kept as a houseplant, the snake plant filters formaldehyde, benzene, and trichloroethylene from indoor air. CAM photosynthesis allows it to release oxygen at night, making it particularly suitable for bedrooms.
The long leaf fibres are traditionally used in West African countries to make bowstrings, mats, and baskets — hence the German common name Bogenhanf (bowstring hemp).
Multiple plants in a room can measurably increase relative humidity and reduce benzene concentrations, as documented by Wolverton for comparable Asparagaceae species.

In Nigeria and other West African countries, leaves are traditionally applied against inflammations and skin conditions — documented ethnobotanically only, no clinical evidence.
TOXIC for dogs and cats (saponins) — vomiting, diarrhoea, drooling. Not hazardous for humans under normal handling; sap may cause skin irritation. ASPCA classification (accessed 2026-08-10): toxic to dogs and cats. The ASPCA classifies the whole genus this way.
No medicinal ingestion recommended; safe as an ornamental plant.
No medicinal ingestion recommended; safe as an ornamental plant.
Keep plant parts away from children — saponins may cause nausea if ingested.
Contraindications
- Do not place within reach of pets (saponin toxicity for dogs and cats).
Harvested part: whole plant (decorative)
- Time of day:
- Morning before strong sun exposure (for fibre harvest).
- Drying:
- Lay leaves flat to air-dry for fibre extraction; then beat out the fibres.
- Time of day:
- Usable year-round as an indoor ornamental.
- Steroidal saponins (dracaenin, sansevierigenin)SaponinContent: 0.5-2 %Leaf
Main active compounds; responsible for pet toxicity (haemolytic properties).
- Organic acids (oxalic acid)OtherLeaf
Present in small amounts; may cause mild irritation on skin contact.
- Flavonoids (quercetin, kaempferol)FlavonoidLeaf
Antioxidant compounds; isolated in ethnobotanical studies.
- Phenolic acids (caffeic acid, chlorogenic acid)Phenolic acidLeaf
Phenolic secondary compounds with anti-inflammatory potential.
- Cellulose fibresPolysaccharideContent: 60-80 %Leaf
Very high proportion of long fibres — basis of the traditional fibre use (bowstring hemp).
- Chlorophyll and carotenoidsOtherLeaf
Photosynthetic pigments; typical leaf chemistry of CAM plants.
