Kidney tonic to detox and support kidney function

Fresh herb tincture from organically grown and wild-harvested herbs.

Alfred Vogel gave a lot of attention to the liver, gallbladder, kidneys and bladder because of their extreme importance in maintaining general health, and developed two excellent herb tonics for these organs, one of which was Nephrosolid.  He always treated the liver and the kidneys simultaneously because their filter systems are so closely related. Most of his patients used these tonics until he was sure that they were on their way to good health. 

Nephrosolid is a combination of four herbs which work synergistically in the body. Apart from Solidago (Solidago virgaurea) the herbs present in this fresh herb tincture are Birch (Betula pendula), Restharrow (Ononis spinosa) and Horsetail (Equisetum arvense).

Benefits and features of A.Vogel Nephrosolid:

  • Fresh herb tincture
  • Made with organically grown or wild-harvested herbs
  • 100% natural
  • Botanical food supplement

Solidago virguarea, also known as Golden Rod, is a herbaceous plant found in temperate countries, often in the natural flora of grassy mountainous areas. The name Solidago means ‘to make whole’. In 15th and 16th Century Europe it was used topically for wound healing but in modern times the main use of Solidago is to help maintain the health of the urinary tract. Golden Rod is the main ingredient in Nephrosolid and has an antiseptic, antispasmodic and anti-inflammatory effect on the urinary tract. It is very efficient for bladder problems, with the potential to prevent kidney stones and even assist in excreting existing ones.

The Birch tree (Betula pendula) is known as ‘The Tree of Life’. It grows well in temperate and Nordic climates and its leaves have been used in herbal supplement combinations to aid detox by supporting the body’s natural elimination of toxins and impurites. One of the lesser ingredients in this combination is Restharrow (Ononis spinosa). It is a commonly found in almost all parts of Europe, West Africa and Asia and has been used traditionally to support bladder health. Horsetail (Equisetum arvense) is another minor but important ingredient in Solidago complex. The plant is said to resemble a horse’s tail and it grows almost everywhere. Although poisonous to grazing animals when eaten in large quantities it has been used by people from as long ago as the Ancient Romans in the form of a tea.

When should I use Nephrosolid?


Healthy people wishing to to revitalise their liver and kidneys can use Nephrosolid together with Boldocynara three times a day for six weeks. For good cleansing, do this three or four times per year.

On chronic medication?

The liver is one of the most important organs in our body for metabolizing or breaking down medications.

People who take regular chronic medication may benefit from taking Nephrosolid (again together with Boldocynara) three times per day for six weeks, after which it should be taken once a day to support the liver and kidneys to process residue from the medication.

For medications to be effective, they have to be absorbed in to the body (usually through the intestine), distributed in the body to where they are needed (usually via the bloodstream), chemically changed or metabolized (often in the liver) and then removed from the body (usually through the urine).

The normal aging process can change the way medications are absorbed, metabolized, distributed and removed from the body. As we age, the liver gets smaller, blood flow to the liver decreases and the chemicals (enzymes) in the liver that break down medications decline. This can result in medications collecting in the liver, thereby causing unwanted side effects and possible damage to the liver. Ironically, due to the increased risk of chronic illness, many older people may be taking various medications, thereby increasing the load placed on their liver and kidneys.

Your hardworking filters

The kidneys work continuously with the liver to purify the blood of waste products and material that can be toxic. Some 800 litres of blood a day pass through the kidneys.

The kidneys also:

  • ensure there is not too much water in the blood otherwise the volume of blood becomes too high for the small arteries and high blood pressure may result.  In order to control the amount of water, the kidneys use a wonderful method of substituting salt, potassium and magnesium with each other inside the cells of the kidneys and in the blood.
  • regulate the water and pH-balance (acid-alkaline levels) in the blood which has a direct influence on the chemical landscape of the whole body.
  • few people know that the kidneys are responsible for new red blood cells produced in the bone marrow. The kidneys can also help to protect protein in the urine, thereby ensuring that we do not lose muscle mass.
  • expel acid from the blood, which helps regulate its acid/alkaline balance.  Most people know these days that a constant acidic state can be detrimental to your general health. It’s important to drink water to help the kidneys. Most people do well with two to three litres of water per day.

Sometimes the body indicates sluggish or overloaded kidneys long before pathological tests do.*

Typical kidney warning signs:

  • High blood pressure
  • Sore joints and muscles
  • Pain on top of the head, behind the neck and along the spine
  • Swollen eyes after sleep
  • Swollen face, hands, legs and ankles
  • Too little or slow urine flow
  • Smelly, dark or discoloured urine, continuous urination
  • Pain on the inside of the left leg
  • Pain behind the knees
  • Eczema, fungus on soles of the feet
  • Burning, sweating, aching soles of feet
  • Sore heels
  • Athlete’s foot
  • Smelly feet

*There is a big difference however between a liver and kidneys that are 'sick' and organs that are overworked, slow and struggling with reduced function.  If the liver and kidneys’ function have deteriorated seriously, a healthcare professional must be consulted for diagnosis and help. The information contained herein, based on advice from renowned Swiss naturopath Alfred Vogel, is concerned with helping to keep these two vital organs healthy with the aim of preventing problems from developing.
