NEDerris
Derris elliptica (Wall.) Benth.
Legume family
Derris roots contain rotenone, a compound toxic to fish and insects, historically used as a botanical insecticide.
Jatropha

NELavender
Lavandula angustifolia Mill.
Lamiaceae family
Lavender (Lavandula angustifolia Mill.) is a low aromatic subshrub of the mint family Lamiaceae, native from north-eastern Spain to Italy according to Kew's Plants of the World Online. True lavender oil is rich in linalool and linalyl acetate (60–75%) with low camphor, giving a clean, sweet floral note; it is a classic perfumery oil and an aromatherapy material studied clinically for anxiety, while the hybrid lavandin (Lavandula × intermedia) accounts for most industrial output.
NELemongrass
Cymbopogon citratus (DC.) Stapf
Poaceae family
Lemongrass (Cymbopogon citratus) is a perennial aromatic grass forming dense tufts 1–1.5 m tall in the grass family Poaceae, native to South Asia (southern India and Sri Lanka) according to Kew's Plants of the World Online and now cultivated throughout the tropics. Its leaf oil is rich in citral — a geranial–neral mixture making up 65–85% — which gives the signature fresh-citrus note; the oil is a cornerstone of the fragrance industry and is being studied clinically for oral health and for controlling bacterial–fungal biofilms.
Mentha canadensis
Mentha canadensis L.
Lamiaceae family
Mentha canadensis is a species of mint native to North America (from the Northwest Territories to central Mexico) and the eastern part of Asia (from Siberia to Java).
Neem
Azadirachta indica A.Juss.
Mahogany family
Neem (Azadirachta indica) is an evergreen tree of the mahogany family with fragrant white flowers and oily drupes; the whole plant contains azadirachtin and is used in traditional medicine and biopesticides, widely grown in South Asia and Vietnam.
Sugarcane
Saccharum officinarum L.
Grass family
Sugarcane (Saccharum officinarum L.) is a perennial grass of the family Poaceae whose jointed stalks grow 2–7 m tall and store sucrose in the internodes, the main raw material of the sugar industry and of bioethanol. According to Kew POWO it is native to New Guinea and was domesticated by Papuans from the wild ancestor Saccharum robustum about 6,000 years ago, then spread across the tropics by Austronesian voyagers. It is the world's largest crop by production quantity (about 1.9 billion tonnes in 2020), with Brazil accounting for roughly 40%. Besides sucrose, cane juice is rich in polyphenols (caffeic, chlorogenic, tricin, apigenin, luteolin) and cane wax contains policosanols (octacosanol) and D-003. In Vietnam it is grown in Thanh Hoa, Nghe An, Phu Yen, Tay Ninh and Hau Giang, among others, for sugar and fresh juice.
Tea tree
Melaleuca alternifolia (Maiden & Betche) Cheel
Myrtaceae family
Tea tree (Melaleuca alternifolia) is a shrub to small tree of the myrtle family (Myrtaceae) native to eastern Australia, famous for a strongly antibacterial essential oil whose main component is terpinen-4-ol. The leaves contain 1–2% oil; under standard ISO 4730, commercial tea tree oil must have at least 30% terpinen-4-ol and no more than 15% 1,8-cineole. The oil is used as an antiseptic, for skin and acne care, hair care, as an antifungal and as a natural cleaner. IUCN lists it as Least Concern (LC).
