Boldo: what it is useful for, benefits and how to consume it
Boldo is a medicinal plant that contains active substances such as boldine or rosmarinic acid and can be used as a home remedy for the liver due to its digestive and hepatic properties, in addition to possessing diuretic, anti-inflammatory and antioxidant properties, for example.
The two most commonly used boldo species are the Chile boldo or true boldo, scientifically called Peumus boldus Molina, which can be found in health food stores and herbalists in the form of dried leaves or in tea sachets, and the Brazilian boldo, Plectranthus barbatus.
Although there are several health benefits, the use of boldo can also have side effects, mainly when consumed in excessive amounts and for more than 20 days, besides being contraindicated in pregnant women, people with acute hepatitis, gallstones, inflammation of the bile ducts or pancreatitis. Therefore, the use of boldo should always be guided by a physician or other health professional with experience in the use of medicinal plants.
The main benefits depend on the species of boldo used, which include:
1. Stimulates liver function

These boldo species are very useful in cases of liver problems that produce symptoms such as headache, cold sweats and malaise.
2. Helps in the treatment of gallbladder problems
Boldo stimulates the production and release of bile by the gallbladder, so it can help in the treatment of gallbladder problems. In addition, boldo helps to normalize the functioning of the gallbladder.
3. Improves digestion

4. Aids in the treatment of gastritis
The alkaloids present in boldo help to control stomach acids and can be very useful in the treatment of gastritis. In addition, the astringent properties of boldo reduce stomach acidity, helping in the treatment of heartburn.
5. Relieves symptoms of food intolerance
Boldo has digestive, anti-inflammatory and antispasmodic properties that can help relieve symptoms of some food intolerances such as poor digestion, intestinal colic and excessive gas production.

Streptococcus pyogenes, which causes throat infection or erysipelas, for example;
Staphylococcus aureus, which causes lung, skin and bone infections.
In addition, boldo essential oil from Chile has antifungal activity mainly for the fungus Candida sp, which can cause mycosis of the skin. However, boldo should not replace any antibiotic and should only be used under medical guidance.
8. It has antioxidant action

Thus, boldo helps prevent and combat diseases associated with oxidative stress caused by free radicals such as atherosclerosis.
9. Improves hangover

How to take boldo
Boldo can be consumed as a tea or juice using the fresh leaves of Brazilian boldo or the dried leaves of Chilean boldo, which can be purchased at health food pharmacies or herbalists. Boldo tea can be prepared immediately before drinking and the leaves should not be boiled together with water, as this may produce a bitter taste.
Another way to use boldo is in immersion baths to soothe and improve symptoms of fatigue and stress, since the aroma of boldo is similar to mint, producing a feeling of well-being. In this case, you can boil 1 liter of water with some boldo leaves for 15 minutes, then add the boldo tea in the bath water and enjoy soaking for approximately 10 minutes.
Possible side effects
Boldo is safe in most adults when consumed for a short period of time. However, if boldo is consumed in excessive amounts or for more than 20 days it can cause liver poisoning, nausea, vomiting, and diarrhea. In addition, boldo can increase uterine contractions and miscarriage, besides causing malformations in the baby, mainly if consumed in the first trimester of pregnancy.
Contraindications
Boldo is contraindicated in infants, children, pregnant women, lactating women and people with acute hepatitis, gallstone, inflammation of the biliary tract, pancreatitis, liver or biliary tract cancer. In case there is suspicion of pregnancy it is recommended that before using boldo it should be confirmed with a pregnancy test, as boldo can cause miscarriage by increasing uterine contractions.
Boldo should not be used to treat infection by the new coronavirus, COVID-19, as there are no studies proving the antiviral action of boldo tea or coronavirus.
