What represents the current primary limitation of clinical evidence regarding Dendrobium for human lung health?

Answer

Absence of large-scale, peer-reviewed human intervention trials

While there is significant evidence from animal models and cellular studies suggesting that Dendrobium possesses antioxidant and anti-inflammatory properties, there is a clear gap in clinical confirmation. No robust, peer-reviewed human trials have definitively proven that supplementation effectively treats or prevents specific established human lung conditions like emphysema or severe asthma. The current findings demonstrate mechanistic plausibility, but the leap to established medical efficacy in human populations remains unverified.
