Frequently asked questions

Everything you need to know before ordering Sylvan Parasite Cleanse Drops.

The product

What is Sylvan?
Sylvan Parasite Cleanse Drops is a herbal food supplement for dogs. Three traditional herbs — Black Walnut hull, Wormwood, and Oregon Grape root — in a duck-flavoured vegetable-glycerin base. One dropper on his food, once a day.

How is Sylvan different from other dog supplements?
Three ingredients, that's it. No 27-item marketing formula, no synthetic sweeteners, no alcohol. UK-made, UK-shipped, formulated with British dog owners in mind.

Is it a wormer?
No. Sylvan is a herbal food supplement, not a veterinary medicine. It sits alongside your vet's routine — many owners use it as a gentle seasonal cleanse between their vet's usual worming schedule.

Using Sylvan

How do I give it to my dog?
Add the dropper straight to his food, once a day. Weight-based dosing on the label (½ dropper for under 10 lb, 1 dropper for 10–35 lb, 2 for 35–75 lb, 3 for over 75 lb).

Will my dog like the taste?
Duck-flavoured, no alcohol. Most dogs eat normally. If he refuses, we refund you — even if the bottle's opened.

How long does one bottle last?
60 ml at 1 ml/day is a 60-day cleanse for a medium dog. Large dogs (over 34 kg) at 3 ml/day finish a bottle in 20 days.

How soon will I see a difference?
Most owners tell us they notice a shift between days 15 and 30 — easier scooting, less paw licking, calmer nights, firmer stools. Full journey is 60–90 days.

Safety

Sylvan is NOT for: pregnant or nursing dogs, puppies under 12 weeks, dogs with a history of seizures (wormwood contains thujone), or dogs with a tree-nut allergy (black walnut). Always consult your vet if your dog is on medication or has a chronic condition.
