Qiao offers a professional interpretation of the method's core logic: "The essence of eco-art therapy is not 'treatment', but reconnection; reconnecting with nature, with yourself, and with your creativity. Much of today's anxiety stems from a sense of loss of control and disconnection. Eco-art therapy lets you touch the soil, smell the grass after rain, and observe the veins of a leaf.

"When your brain switches from ruminating about the past or worrying about the future to being fully present in the moment, anxiety naturally finds an outlet," Qiao says.

As another important carrier of emotional healing, fragrance has solid scientific support for its therapeutic effects.

"Smell is the only sense that goes directly to the amygdala — the emotional center of the brain — without passing through the thalamus. This means it can reach your heart before you even have time to rationally think," Qiao states.

In clinical interventions, scent is used as a crucial "emotional anchor". Qiao explains that her team does not simply use lavender to calm people; instead, it guides patients to form an association with a specific natural scent, such as citrus or cedar, while in a deeply relaxed state. Later, when they feel anxious in their daily lives, that scent acts like an "emotional switch", helping them regain calm quickly.

"In this sense, fragrance is not a 'placebo', but a direct shortcut to the emotional center," she adds.
