Laxa-Herb Herbal Formula Supplement
Verified Jun 11, 2026
This is a liquid herbal supplement for dogs and cats designed to act as a short-term laxative and hairball aid. It uses herbs like cascara sagrada, Chinese rhubarb, ginger, and licorice root to gently stimulate the digestive tract. It’s intended for occasional use when constipation or hairballs are a concern, not as an everyday product.
This is a targeted, short-term herbal supplement aimed at relieving constipation and helping hairballs pass in both dogs and cats. The formula relies on traditional laxative herbs rather than pharmaceutical agents, which some owners prefer. It’s best used cautiously, for brief periods and ideally under veterinary guidance, especially if constipation is recurrent.

At a Glance
KibbleLab Review
Strengths
- Multiple traditional herbal laxatives (cascara sagrada and Chinese rhubarb) combined with ginger and licorice are designed to stimulate gut movement and reduce discomfort.
- Liquid tincture format allows fairly precise dosing by body weight in both dogs and cats and can be given in food, by mouth, or diluted in water.
- Includes soothing and digestive-supportive herbs like ginger and raspberry leaf, which may help with mild gastrointestinal upset associated with hairballs or constipation.
Considerations
- This is not a complete and balanced diet but a short-term supplement; ongoing constipation or frequent hairballs should be evaluated by a veterinarian to rule out underlying disease.
- Herbal laxatives like cascara and rhubarb can be quite potent; overuse or long-term use may cause diarrhea or electrolyte disturbances, so following dosing directions and limiting duration is important.
- Contains multiple plant ingredients, which may not be suitable for pets with known sensitivities to specific herbs or botanicals.

Top 5 Ingredients Explained
01
Cascara Sagrada
Cascara sagrada is an herbal bark used as a stimulant laxative in some pet supplements rather than a nutrient or protein source, and it is sometimes included for short-term relief of constipation in dogs and occasionally cats. It can be effective for brief use but may cause abdominal cramping, diarrhea, dehydration and electrolyte imbalances, can interact with medications, and should not be used long-term or in pregnant, dehydrated animals or those with bowel obstruction or inflammatory bowel disease—always consult your veterinarian before use.
02
Chinese Rhubarb
Chinese rhubarb (Rheum spp.) is used in pet products as a botanical/herbal ingredient for its traditional medicinal actions—most notably mild laxative, anti-inflammatory and antioxidant effects—rather than as a source of macronutrients. While it may help with occasional constipation or digestive support in dogs and cats when given in carefully controlled amounts, it contains anthraquinones and oxalates that can cause diarrhea, electrolyte imbalance or more serious toxicity if overused, and should be avoided in pregnant or dehydrated animals and used only under veterinary supervision.
03
Ginger
Ginger is commonly added to pet foods and treats as a natural flavoring and functional ingredient to support digestion and reduce mild nausea, with active compounds like gingerols providing modest anti-inflammatory and antioxidant effects. It can be beneficial for dogs (and occasionally cats) with motion sickness or stomach upset when used in small amounts, but high doses should be avoided and caution is advised for pets on anticoagulant medications, pregnant animals, or those with known sensitivities due to potential effects on clotting and occasional gastrointestinal irritation.
04
Licorice
Licorice is used in pet foods and supplements primarily as a flavoring and herbal ingredient with mild demulcent and anti‑inflammatory properties rather than as a significant source of nutrients. While small amounts may help soothe the gastrointestinal tract, licorice contains glycyrrhizin which can cause sodium retention, potassium loss and high blood pressure, so it should be used cautiously and avoided in pets with heart, kidney or liver disease, hypertension, pregnancy, or when taking diuretics or corticosteroids.
05
Lobelia
Lobelia is not a standard pet food ingredient and is sometimes encountered only in herbal supplements rather than nutritional pet diets; it has historically been used in herbal medicine but provides no meaningful nutritional protein, fiber, vitamin, or mineral content for dogs or cats. It contains active alkaloids (e.g., lobeline) that can cause vomiting, tremors, respiratory distress, or more serious toxicity in pets, so it should be avoided in pet foods and any use as a therapeutic herb should be undertaken only under veterinary guidance.
