    De Groene Os Drainage Compositum Dog/Cat 50 ml Groene Os Drainage Compositum Dog/Cat 50 ml is a supplement with a broad cleansing effect and a positive influence on metabolism, kidneys, and digestion for dogs and cats. Perfect for a cleansing cure. Drainage Compositum boosts the body's cleansing process by assisting the liver in removing waste products and positively influencing the kidneys. This recipe contains ingredients that activate the immune and lymphatic systems, promote digestion, and stimulate metabolism, thus preventing the storage of new waste products. Therefore, it helps with sensitive skin, is good for healthy digestion, and can be used as a cleansing cure. Drainage Compositum is composed of a wide range of ingredients with a specific function. For example, artichoke has liver-protective properties and supports normal fat metabolism. It supports the absorption of nutrients and protects the gastric mucosa. Birch is good for the kidneys and urinary tract. Uva ursi supports a healthy environment in the bladder and helps maintain normal fluid balance. Canadian goldenrod contains the potent ingredients hydrazine and berberine. It supports bladder resistance. The wild pansy is rich in flavonoids.

Arctium lappa also helps restore the gut flora. Goldenrod supports the elimination of waste products through its blood-purifying effect and by supporting fluid balance. Javanese kidney tea/cat's whiskers is also called kidney stone breaker. It supports healthy kidney function. Calamus supports the secretion of digestive juices and thus digestion. Cat's claw has a broad, supportive effect. Besides maintaining normal resistance, this herb cares for the mucous membranes. Blackcurrant buds are used to support the adrenal cortex in releasing its own cortisol. This helps to soothe sensitive skin and relieve itching. The use of buds is also known as gemmotherapy. Milk thistle protects the liver due to its strong antioxidant properties. Dandelion supports healthy liver and gallbladder function. It aids digestion and is good for fluid balance. Echinacea is a well-known herb for supporting the immune system. Please note: During the use of Drainage Compositum, waste products are released to be eliminated by the excretory organs. These waste products are transported through the bloodstream. The amount of waste products in the blood will temporarily be higher due to the use of Drainage Compositum. This can cause a feeling of fatigue and animals may become somewhat lethargic. Drainage Compositum may initially cause a slight worsening of existing symptoms. This potential worsening should never be so severe that the animal becomes truly ill. By gradually increasing the dosage (see instructions for use), you can minimize the risk of initial symptom worsening. If in doubt, contact a veterinarian.
