-"...many lemon yellow flowers emitting this scent marker of Tekadu [in Papua New Guinea]. In chemical and olfactory terms, this scent is mainly based on methyl benzoate, methyl salicylate and its methylated product, comparatively high levels of lavandulol and ist acetate, geraniol, 2-phenylethyl alcohol and its acetate, and beta-ionone." \\ [Roman Kaiser, Meaningful scents around the world, pp.80 and 216]+"...many lemon yellow flowers emitting this scent marker of Tekadu [in Papua New Guinea].

 Uses. Areca seed is used for centuries as mild psychostimulant, but also as digestive aid and vermifuge. The typical betel quid is regularly chewed by many (appr. 200 million, 1998) peoples of Southeast Asia. A betel quid is formed by wrapping slices of the Areca seed together with lime (calcium hydroxide), cinnamon and other spices, in a leaf of betel pepper (Piper betle L.). Betel chewing is often a social affair, for instance following a meal. Nut decoctions are used as anthelminthic, especially to remove tapeworms. \\ Uses.

 Side effects. The coloring matter present in the seeds turns the saliva bright red. Excessive use for years may stain the teeth red-brown to nearly black. Salivation and inappetence occur. Betel use is associated with oral leukoplakia, submucous fibrosis, and squamous cell carcinoma. [Norton SA, J. Am. Acad. Dermatol., 38(1), (1998), 81-88] \\ Side effects.
