Liquiritin apioside has antioxidant property by inducing glutathione (GSH) biosynthesis via the inhibition of cytokines and protected lung epithelial cells against cigarette smoke-mediated oxidative stress, might be as protective agent against epithelial injury in COPD. Liquiritin apioside is a glycoside and a member of flavonoids.

Guaifenesin is also a centrally acting skeletal muscle relaxant. Guaifenesin has antitussive effects, it can inhibit the cough-reflex sensitivity in acute viral cough, it is an expectorant commonly by thinning the mucus or phlegm in the lungs.

Capsaicin, the main pungent ingredient in 'hot' chilli peppers, is a TRPV1 agonist with EC50 of 0.29±0.05 μM in HEK293 cells, which elicits a sensation of burning pain by selectively activating sensory neurons that convey information about noxious stimuli to the central nervous system, it may used as a pain therapy by the long-lasting and inhibitory effects on persistent pain. Capsaicin has antioxidant activity , it is more effective than melatonin in suppressing the formation of lipid hydroperoxides, it also reduces anxiety-like behaviours in rats and may be an admissible drug candidate for treating endometriosis. Capsaicin is a capsaicinoid. It has a role as a TRPV1 agonist, a non-narcotic analgesic and a voltage-gated sodium channel blocker.

Baccatin III, which is the precursor for the semisynthesis of paclitaxel,exerts anti-tumor immunomodulatory activity in very low doses (0.05-0.5mg/kg),it reduces tumor progression by inhibiting the accumulation and suppressive function of MDSCs. Baccatin III also exerts immunomodulatory activities in vivo as well as in vitro on the MHC-restricted antigen presentation. Baccatin III is a tetracyclic diterpenoid isolated from plant species of the genus Taxus. It has a role as a plant metabolite. It is a benzoate ester, an acetate ester and a tetracyclic diterpenoid. It derives from a hydride of a taxane.
