Sesamin is the most prominent lignan compound found in sesame seeds, one of the two highest sources of lignans in the human diet (the other being flax). Sesamin is catered to be a nutritional supplement that confers antioxidant and antiinflammatory effects (if touting its health properties) or possibly being an estrogen receptor modulator and fat burner (if targeting atheltes or persons wishing to lose weight). Sesamin has a few mechanisms, and when looking at it holistically it can be summed up as a fatty acid metabolism modifier. It appears to inhibit an enzyme known as delta-5-desaturase (Δ5-desaturase) which is a rate-limiting enzyme in fatty acid metabolism; inhibiting this enzyme results in lower levels of both eicosapentaenoic acid (EPA, one of the two fish oil fatty acids) as well as arachidonic acid, and this mechanism appears to be relevant following oral ingestion. The other main mechanism is inhibiting a process known as Tocopherol-ω-hydroxylation, which is the rate limiting step in the metabolism of Vitamin E; by inhibiting this enzyme, sesamin causes a relative increase of vitamin E in the body but particularly those of the gamma subset (γ-tocopherol and γ-tocotrienol) and this mechanism has also been confirmed to be active following oral ingestion. Sesamin is a potent and specific inhibitor of delta 5 desaturase in polyunsaturated fatty acid biosynthesis. Sesamin inhibits a particular CYP3A enzymes that is involved in vitamin E metabolism, where the enzyme initially ω-hydroxylates vitamin E (required step) and then the rest of vitamin E is subject to fat oxidation. By inhibiting this step, sesamin causes an increase in circulating and organ concentrations of vitamin E. Sesamin is thought to have PPARα activating potential in the liver, but it is uncertain how much practical relevance this has in humans due to this being a mechanism that differs between species.

Honokiol is a biphenolic natural product isolated from the bark and leaves of Magnolia plant spp. Honokiol possesses anti-carcinogenic, anti-inflammatory, anti-oxidative, anti-angiogenic as well as the inhibitory effect on malignant transformation of papillomas to carcinomas in vitro and in vivo animal models without any appreciable toxicity. Honokiol affects multiple signaling pathways, molecular and cellular targets including nuclear factor-κB (NF-κB), STAT3, epidermal growth factor receptor (EGFR), cell survival signaling, cell cycle, cyclooxygenase and other inflammatory mediators, etc. Honokiol can permeate the blood-brain barrier and the blood-cerebrospinal fluid to increase its bioavailability in neurological tissues. Diverse studies have provided evidence on the neuroprotective effect of honokiol in the central nervous system, due to its potent antioxidant activity, and amelioration of the excitotoxicity mainly related to the blockade of glutamate receptors and reduction in neuroinflammation. Honokiol can attenuate neurotoxicity exerted by abnormally aggregated Abeta in Alzheimer's disease. Honokiol is being developed by Huons as HL tablet for the treatment of alcoholic and non-alcoholic fatty liver.

Rosmarinic acid (α-o-caffeoyl-3,4-dihydroxyphenyllactic acid; RA) is a naturally occurring hydroxylated compound commonly found in species of the subfamily Nepetoideae of the Lamiaceae and Boraginaceae, such as Rosmarinus officinalis, Salvia officinalis, and Perilla frutescens. RA is biosynthesized from the amino acids L-phenylalanine and L-tyrosine by eight enzymes that include phenylalanine ammonia lyase and cinnamic acid 4-hydroxylase. Recently, RA and its derivatives have attracted interest for their biological activities, which include anti-inflammatory, anti-oxidant, anti-angiogenic, anti-tumor, and anti-microbial functions. Clinically, RA attenuates T cell receptor-mediated signaling, attenuates allergic diseases like allergic rhinitis and asthma, and 2,4-dinitrofluorobenzene-induced atopic dermatitis-like symptoms, protects from neurotoxicity, and slows the development of Alzheimer's disease. Rosmarinic Acid seems to be able to suppress 5-lipoxygenase and 5-HETE synthesis (a pro-inflammatory compound in the omega-6 metabolic chain). Rosmarinic acid appeared to be effective in suppressing allergies in a dose-dependent manner, with 30% of the placebo group reporting symptom relief compared to 55.6% of the 50mg group and 70% of the 200mg group.

Cytisine ( aka baptitoxine and sophorine) is a naturally occurring alkaloid that can be found in several plant genera, such as Laburnum and Cytisus of the family Fabaceae. It has been found to be clinically superior to nicotine replacement therapy for the cessation of smoking. It is available in Eastern Europe under the brand names Tabex and Desmoxan and in Canada under the brand name Cravv. However certain undesirable side effects exist, Cytisine can interfere with breathing and cause death (LD50 i.v., in mice, is about 2 mg/kg) and Cytisine is also teratogenic. Cytosine is an α4β2 nicotinic Acetylcholine receptor agonist. In addition to clinical use as a smoking cessation aid, It has demonstrated anti-depressant effects in mice.

Caffeic acid is an organic compound that is classified as a hydroxycinnamic acid. Caffeic acid is naturally found in many agricultural products, such as fruit, vegetables, wine, olive oil, and coffee, and therefore, significantly present in human diet. Caffeic acid has been reported to have a wide variety of biological activities, including antioxidants, antithrombosis, antihypertensive, antifibrosis, antiviral and anti-tumor properties. Caffeic acid can be effectively employed as a natural antioxidant in various food products such as oils. Caffeic acid exhibits potent anticancer effect in HT-1080 cell line and that it may be used as an anticancer agent. Caffeic acid showed neuroprotective action against oxidative and DNA damage produced in the kindling epilepsy model, although they did not produce antiepileptogenic effect in vivo. Caffeic acid was effective in patients with primary immune thrombocytopenia. Detected in clinical trial caffeic acid-related adverse events were: mild nausea and elevation of liver enzymes.

Allantoin is a metabolic intermediate of a wide variety of organims: from bacteria to vegetals and animals. Allantoin is a skin active ingridient with keratolytic, moisturizing, anti-irritant properties, promotes renewal of epidermal cell and accelerates wounds healing. Allantoin possesses one chiral center thereby exists in the two enantiomeric forms R-(-) and S-( ). Enzymes that catalyze the formation of (S)-allantoin from the product of the urate oxidase reaction have been identified. The two proteins encoded by mouse genes catalyze two consecutive steps following urate oxidation to 5-hydroxyisourate (HIU): hydrolysis of HIU to give 2-oxo-4-hydroxy-4-carboxy-5-ureidoimidazoline (OHCU) and decarboxylation of OHCU to give S-( )-allantoin. Urate oxidation produces racemic allantoin on a time scale of hours, whereas the full enzymatic complement produces dextrorotatory allantoin on a time scale of seconds. Scioderm is developing Allantoin (Zorblisa; SD-101), as a novel topical therapy for patients with epidermolysis bullosa.

Diethyltoluamide (DEET) is an insect repellent used to keep insects away. This product is effective against mosquitoes, biting flies (gnats, sandflies, deer flies, stable flies, black flies), ticks, harvest mites, and fleas. DEET is absorbed through the skin. DEET has few adverse effects when applied as directed. The most common problem is local skin irritation, including erythema and pruritis, at the site of application.

Perflunafene is a perfluorocarbon that can absorb, transport, and release oxygen and carbon dioxide. Perflunafene is a can be used as an alternative to red blood cell preparations to improve gaseous transport, in particular oxygen supply, to the tissues. Intra-ocular injection of perflunafene is used to provide temporary tamponade in ophthalmic procedures such as retinal re-attachment. Perflunafene and perfluamine have been used together for their oxygen-carrying properties in blood substitute preparations and to prevent myocardial ischaemia during percutaneous transluminal coronary angioplasty.

Zeaxanthin is one of the most common carotenoid alcohols found in nature. It is synthesized in plants and some micro-organisms. Lutein and Zeaxanthin are found in the macula of the human retina, as well as the human crystalline lens. They play a role in protection against age-related macular degeneration (ARMD) and cataract formation. The antioxidant properties of lutein and zeaxanthin together with ocular antioxidants (selenium, zinc, copper, vitamin A, C, E, etc.) inhibit free radical damage caused by light and oxygen. Zeaxanthin supplements are typically taken on the supposition of supporting eye health. It is is Generally Recognized As Safe by FDA.
