The Science Behind Tulsi Oxygen Benefits
How Tulsi Purifies Indoor Air Naturally
Tulsi is known to absorb harmful toxins such as:
Carbon dioxide (CO₂)
Sulfur dioxide
Carbon monoxide
Formaldehyde
Through photosynthesis, Tulsi converts these toxins into oxygen, making your home environment fresher and healthier.
Does Tulsi Release Oxygen at Night? (Myth vs. Fact)
Many believe Tulsi gives oxygen 24/7. The truth is:
Tulsi primarily produces oxygen during the day via photosynthesis.
At night, it switches to respiration, consuming oxygen and releasing CO₂.
Some research suggests Tulsi may release trace oxygen at night via Crassulacean Acid Metabolism (CAM) — a process also found in Aloe Vera and Snake Plant.
