The prevalence of worm infections in dogs presents a significant health concern, prompting ongoing efforts to develop effective treatments. Traditional deworming medications have encountered challenges with drug resistance, prompting exploration into alternative approaches. Among these alternatives, herbal dog dewormers have garnered attention for their potential efficacy and reduced risk of resistance development.
In this study, we investigate the effectiveness of three herbal remedies – garlic bulb extract, onion bulb extract, and jatropha leaf extract – in combatting worm eggs and larvae in dogs, aiming to assess their viability as herbal dog dewormers.
The study
The study focused on ethanol and water extracts from garlic bulbs, onion bulbs, and Jatropha leaves. These plants were selected based on traditional use as natural anthelmintics and promising initial studies. In laboratory experiments, researchers first tested whether the six extracts could kill worm larvae and prevent worm eggs from hatching.
The onion bulb ethanol extract showed the most potent results overall. It completely stopped the hatching and development of both roundworm and hookworm eggs at high concentrations between 10,000 and 1,250 micrograms/millilitre. The garlic bulb ethanol extract also entirely prevented hookworm eggs from hatching at those doses but was less effective against roundworm eggs. Both onion and garlic extracts significantly reduced the survival of hookworm larvae. Unfortunately, the Jatropha leaf ethanol extract could not dissolve in water for testing.
positive lab results
With positive lab results, researchers evaluated the onion bulb ethanol extract in 15 puppies with natural gut worm infections. After seven days, puppies treated orally with a 6 mg/kg body weight dose showed a 47% decrease in hookworm egg counts compared to untreated controls. However, the extract only caused a negligible reduction in roundworm eggs passed in the puppies’ faeces. This indicates that the active anthelmintic ingredients in onion bulbs may have selective efficacy against different parasite species.
To assess safety, acute toxicity tests gave rats extremely high single doses of 2,000-5,000 mg/kg onion extract without any adverse effects. This suggests a low risk of toxicity at the effective dose used in puppies. Monitoring blood parameters in treated puppies also revealed positive changes like decreased white blood cell counts and increased red blood cell counts. Such alterations likely reflect a reduction of inflammation and anaemia caused by the worms.
In summary, the Kenya study demonstrates both garlic and onion bulb extracts can inhibit dog worm development and survival in vitro. Oral onion extract administration showed moderate in vivo potency against puppy hookworm infections without toxicity.
Researchers concluded that allium plants seem promising for managing veterinary parasitism. Follow-up studies should now explore the efficacy of higher extract doses, repeated treatments, combination formulas, and delivery methods. Attempts to isolate the bioactive chemicals will also facilitate understanding the mechanism of action against worms. Much work remains before allium extracts become viable natural alternatives to synthetic dewormers. But these early findings provide hope that traditional herbal remedies could someday fill arsenal gaps created by rising drug resistance.

Herbal Remedies for Controlling Dog Worms
Worm infections pose significant threats to dogs, necessitating effective treatments. However, the rise of resistance to conventional medicines has spurred interest in herbal remedies. Researchers investigated the potential of three plant extracts – garlic bulb, onion bulb, and jatropha leaf – in combating worm eggs and larvae.
Extract Effectiveness
- Onion Bulb Extract: It has demonstrated the highest efficacy at adequate doses, preventing worm egg hatching and larvae survival.
- Garlic Bulb Extract inhibited egg hatching and larvae survival, albeit less effectively than onion extract.
- Jatropha Leaf Extract: Showed larvicidal properties but lacked efficacy in preventing egg hatching.
Clinical Trials and Findings
Clinical trials administering onion bulb extract to worm-infected puppies revealed a notable reduction in hookworm eggs, though its impact on roundworms was limited.
Experiments found:
- Onion bulb extract was best at preventing worm eggs from hatching and larvae from surviving. When given at a high enough dose, it stopped all worm eggs from developing.
- Garlic bulb extract also prevented eggs from hatching and larvae from surviving, but it was not as strong as onion extract.
- Jatropha leaf extract killed larvae but did not stop eggs from hatching.
Researchers then tested giving onion bulb extract to puppies with worm infections. The extract reduced the number of hookworm eggs by 47% compared to untreated puppies. It did not minimise roundworm eggs very much.
Conclusion and Future Directions
In conclusion, this study sheds light on the potential of herbal dog dewormers as alternative treatments for canine worm infections. Among the extracts tested, onion bulb extract emerged as the most promising, demonstrating significant efficacy in preventing worm egg hatching and larvae survival, particularly against hookworms.
While garlic and jatropha extracts also exhibited some effectiveness, further research is warranted to optimize dosages and elucidate their mechanisms of action. The findings underscore the need for continued exploration of herbal remedies as viable options in the fight against dog worm infections, offering hope for improved deworming strategies in veterinary practice.
