Nonionic emulsifying wax is incompatible with tannin, phenol and phenolic materials, resorcinol, and benzocaine. It may reduce the antibacterial efficacy of quaternary ammonium compounds. 

Lippia javanica Spreng. umsutane, fever tree] (Verbenaceae) leaves are used for psychotropic behaviour. The leaf contains alkaloids, polyphenols, saponins and tannins (18) and essential oils (28,65). The root decoction is also nsed for kidney problems (12). Its essential oil is antibacterial and... 

Anthospermum rigidum Eckl. Zeyh. [sambulela] (Rubiaceae) leaf infusion is also used for pubic lice. The leaf contains flavonoids, polyphenols and tannins (75). Studies have also shown that apart from the antibacterial properties of these plants, they also have additional medicinal values. The root bark of Andrachne ovalis shows insecticidal activity and is a remedy for snake bites and epilepsy (16,28). The alcohohc extract of the leaves is strongly molluscicidal and can be used in the vector control of hilharzia (67). The leaf decoction is used for persistent dizziness (11). The stem bark contains alkaloids, anthranoids, cardenolides and polyphenols. The root bark contains alkaloids, cardenohdes, polyphenols and saponins (50).

UVA URSI, Bearberry Leaf, Uvae ursi folium, Arctostaphylos uva ursi (L.) Spreng, family Ericaceae. The dried leaves constitute the drug. Besides arbutin (not less than 8%) and methylarbutin, the leaves also contain tannins. 1.5-4.0g dried leaves given by infusion three times daily gives an antiseptic effect (by hydrolysis to hydroquinone) in the urinary tract, when the urine is kept alkaline. The maximal antibacterial effect is reached about 3 hours after administration.

Tannins are naturally occurring water-soluble polyphenolic compoimds, and it has been reported that they show their anti-HIV activity by inhibiting polymerase and ribonuclease activities of HIV-1 RT. Phlorotannins are tannin derivatives which contain several phloroglucinol imits linked to each other in different ways and formed by the polymerization of phloroglucinol (1,3,5-trihydroxybenzene) monomer units and biosynthesis through the acetate-malonate pathway. So far, phlorotannins mostly have been isolated from red and brown alga. Numerous bioactivities of phlorotannins have been reported up to date such as antioxidant, antiinflammatory, antibacterial, and anti-MMP activities (Kim et al., 2006 Nagayama et al., 2002).
