Gen info
- Paederia foetida belongs to the Rubiaceae family and is one among the 30 species in the Paederia genus.
- Paederia is a genus of flowering plants in the madder family, Rubiaceae. They are commonly known as sewer vines because of the strong odor when leaves or stems are crushed or bruised.
- The genus name Paederia derives from the Greek word "paederos" meaning "opals."The species name "foetida" derives from Latin, meaning "stinky" or "foul smelling."
- Kantutan, a Filipino local name for the plant, is likely a ribald sexual reference to the smell that the leaves or stems exude when crushed.

Kantutan is a climbing, herbaceous. hairy or smooth slender vine. Leaves are ovate to oblong-ovate, 6 to 10 centimeters long, 3.5 to 5 centimeters wide, pointed at the tip, rounded or slightly heart-shaped at the base, emitting a distinct foetid odor when crushed. Flowers are stalkless, borne in axillary, lax, peduncled inflorescences. Calyx is small and 5-toothed. Corolla is about 1 to 3 centimeters long, somewhat cylindrical, pale purple to nearly white outside, deep purple and villous inside; limb is spreading with 5 undulate lobes. Fruit is somewhat rounded, about 5 millimeters in diameter.

- Native to the Philippines.
- Throughout the Philippines in thickets at low and medium altitudes, ascending to 1,500 meters.
- Also native to Andaman Is., Assam, Bangladesh. Borneo, Cambodia, China, Hainan, Himalaya, India, Japan, Jawa, Korea, Laos, Lesser Sunda Is., Malaya, Maluku, Myanmar, Nansei-shoto, Nepal, Nicobar Is., Sri Lanka, Sulawesi, Sumatera, Taiwan, Thailand, Tibet, Vietnam.

The phenolic content correlated with total antioxidant activity (TAA). The methanol extract exhibited the highest extraction ability for TPC (total phenolic content), TFC (total flavonoid content), and TAA (total antioxidant activity) while aqueous extracts were superior for TTC (total tannin content). The ME also showed higher antioxidant activity with DPPH, ABTS, SO and FRAP. (30)
• Analgesic / Sedative / Leaves: Study evaluated various leaf extracts of P. foetida for analgesic and neuropharmacologic potential. Ethanolic extracts significantly inhibited nociceptive response in both acetic acid and formalin tests on mice. Aqueous extracts exhibited mild sedative effect while ethanol and EA extracts showed little sedative anxiolytic effect in hole cross, open field, and elevated plus maze tests on mice. (31)
• Cardiotonic / Cardioprotective / Leaves: Study evaluated P. foetida ethanol and hydroalcoholic leaf extracts for cardiotonic activity by Isolated Frog Heart Perfusion Technique and protective effects using Isoproterenol induced cardiotoxicity in Wistar albino rats. Results showed significant positive inotropic and negative chronotropic effect similar to standard drug digoxin. Cardiotonic activity was further confirmed by a significant (p<0.05) decrease in membrane Na+K+ATPase and Mg++ATPase and increase in Ca++ATPase. The extracts also significant restored (p<0.05) levels altered by isoproterenol. Activities may be attributed to cardiac and iridoid glycosides. (see constituents above) (32)

The qNMR method was deemed accurate and reliable for quality control of P. foetida and other medicinal plants without extensive sample preparation. (
• Antihyhyperglycemic / Stems: Study evaluated the crude methanolic extracts of leaves of Madhuca indica and stems of Paederia foetida. Crude methanol extract of stems of Paederia foetida exhibited significant and dose dependent reductions in serum glucose levels when administered to glucose-loaded mice. The extract at doses of 50, 100, 250, and 500 mg/kbw reduced serum glucose levels by 7.7, 25.3, 31.0 and 31.2%, respectively. (
• Enzymatic Activity / Antidiabetic Inhibitors / Twigs: Study evaluated the
α-amylase and α-glucosidase enzymatic inhibition activity of Paederia foetida twigs extract and identified the metabolites responsible for the bioactivity by GC-MS metabolomics profiling. Results revealed the presence of 12 bioactive compounds. α-Amylase-n-hexadecanoic acid exhibited the lowest binding energy of  -2.28 kcal/mol with two hydrogen bonds residue. The binding interactions of α-glucosidase-n-hexadecanoic acid complex ligand also showed the lowest binding energy among 5 major compounds with energy value of -4.04 kcal/mol. Study provides informative data on potential antidiabetic inhibitors identified in Paederia foetida twigs, indicating the plant's therapeutic effect properties to manage diabetes. (see constituents above) (42)
• Renoprotective Activity / Antioxidative / Leaves: Study evaluated the effect of methanolic leaf extract of P. foetida on alloxan-induced diabetic renal oxidative stress and NF-kB dependent reno-inflammatory events in rat. MEPF treatment significantly reduced hyperglycemia, serum creatinine, BUN, bilirubin, AST, ALT, triglycerides and total cholesterol in diabetic rats and significantly restored GFR and serum albumin level, along with significant augmentation of enzymatic and non-enzymatic antioxidant machineries. It also significantly lowered lipid peroxidation evidenced by decreased concentration of thiobarbituric reactive substances (malondialdehyde, MDA) in the renal tissue of treated diabetic groups. MEPF treated animals exhibited low serum concentrations of IL-6, IL-1ß, and TNF-
α. There was dose dependent inhibition of NF-kB activation in the diabetic kidney, more prominent at a dose of 500 mg/kg. Histopathological examinations confirmed the nephroprotective action. (43)
• Antioxidant / Analgesic / Antimicrobial / Anthelmintic / Aerial Parts: Study evaluated the antioxidant, analgesic, antimicrobial, and anthelmintic activities of ethanol extract of aerial parts of P. foetida. The extract showed free radical scavenging properties, which on DPPH assay showed IC50 of approximately 75.52 µg/mL, compared to vitamin C at 15.78 µg/mL. Total phenolic content and total tannin content were 55.36 mg and 36 mg GAE/gm of dried plant extract. Total flavonoid content was 60 mg QE/gm dried extract. The extract showed antibacterial activity against S. aureus, V. cholerae, and P. aeruginosa species. Extract showed significant (p<0.01) acute peripheral analgesic activity at doses of 250 mg/kg (34.66% writhing inhibition) and 500 mg/kg (65.91% writhing inhibition) by acetic acid induced writhing reflex in mice compared to Diclofenac sodium (79.55%). Extract showed anthelmintic activity with dose dependent decrease in paralysis and death time of parasites (Trematode and Nematode). (44)
• Gold and Silver Nanoparticles / Photocatalytic / Antimicrobial: Study reports on the facile biogenic synthesis of gold and silver nanoparticles using aqueous extracts of P. foetida as reducing as well as stabilizing agent. Biogenic silver NPs showed strong antimicrobial activity against B. cereus, E. coli and A. niger. Biogenic gold nanoparticles did not show any antimicrobial activity. (45)
• Antibacterial / Antibiofilm Potential / Leaves: Study evaluated the antibacterial and antibiofilm properties of P. foetida. The methanolic extract of dried leaves showed antibacterial activity against E. coli and Mycobacterium smegmatis. Of six fractions tested, two showed antibacterial properties against two tested bacteria. More than 50% of M. smegmatis biofilm and 30% of E. coli biofilm formation were inhibited by the extract and active fractions. Two MIC of the extract and fractions destroyed the established biofilm mass of the tested bacteria. Linolenic acid, carotenoid, and icosanamide were detected in F5 fraction. Phaeophytin A was detected in F6 fraction. (46)
• Amelioration of Lead Toxicity: Study evaluated the protective effects of P. foetida extract on the hematological system and renal and liver function in male Wistar rats exposed to lead poisoning.
The PF extract at 100, 500, and 1,000 mg/kg significantly (p<0.05) improved the harmful effects of lead administration on body weight, liver, and kidney, as well as hematological indices. Results showed potent protective effect against lead-induced toxicity. Since lead exposure causes oxidative stress, an exogenous chelator with antioxidant activity, such as the low cost PF extract, could be a promising agent for amelioration of lead toxicity. (47)
• Antidiarrheal / Leaves: Study evaluated the antidiarrheal mode of action of extracts of leaves of Paederia foetida using castor oil-induced diarrhea, castor oil-induced enteropooling and gastrointestinal motility test in Swiss albino mice. Loperamide was used as standard. While both extracts showed potential antidiarrheal activity, the ethyl acetate extract showed more significant activity than the aqueous extract. Mode of activity was attributed to both inhibition of gastrointestinal motility and enteropooling activities.   (48)
• Skin Wound Healing / Leaves: Study evaluated the effect of P. foetida flower absolute (PFFA) on skin
wound healing and skin barrier-linked responses in human epidermal keratinocytes (HaCaT cells). PFFA contained 23 components and increased the proliferation and sprout outgrowth of HaCaT cells and modestly increased migration. Results suggests PFFA may promote skin wound repair by stimulating migratory and proliferative activity (probably through the AKT/MAPK pathway), collagen synthesis, and skin barrier repair by upregulating the expressions of filaggrin in epidermal keratinocytes. Results suggest PFFA may be useful for developing agents that enhance skin wound and barrier-repair functions. (49)
• Antibacterial Endophytic Fungi / Leaves: Endophytic fungi that live in plant tissue produces secondary metabolites that potentially act as an antibacterial compound. Study sought to obtain endophytic fungi isolates from P. foetida capable of producing secondary antibacterial metabolites.  Results showed SL1, SL4, and SL6 secondary metabolites showed moderate to strong antibacterial activities against S. aureus ATCC6 538 and E. coli ATCC8739. The secondary metabolites extract of SL1 isolate were alkaloid and tannin. SL4 were phenolic and alkaloid while SL6 isolate were alkaloid and terpenoid. The endophytic fungi SLI isolate was identified as Fusarium sp., SL4 as Dematophora sp., and SL6 isolate as Acremonium sp. (
• Antimelanogenic Effect / Skin Whitening Effect: Study evaluated the anti-melanogenic effect of P. foetida extract. B16F10 cells, which are murine melanoma cells, were stimulated with alpha-melanocyte-stimulating hormone (α-MSH) for an in vitro experiment. Extract treatment in B16F10 cells with activated malanogenesis due to stimulants showed PFE significantly inhibits melanin content and intracellular tyrosinase activity within a range that does not cause cytotoxicity. Mechanism studies showed PFE processing inhibited the activation of melanin production by regulating phosphorylation of each mitogen-activated protein kinase (MAPK) family in the MAPK signaling pathway. The PFE did not have any side effects on human skin. Results suggest PFE has great potential as a skin whitening agent and in the prevention of hyperpigmentation disorders. (
• Antibacterial Effect on E. coli Growth / Leaves: Study evaluated the effect of ethanol extract of P. foetida on the growth of E. coli using serial disc diffusion method. Results showed inhibition of bacterial growth, and the higher the concentration, the greater the inhibition zone. (
• Antidiabetic / Antioxidative / Leaves: Study evaluated methanolic extracts of different plant parts.
