What is Xiaoyaosan used for?

While few studies strongly support the use of Xiaoyaosan (most of which are animal- or laboratory-based), there are a few herbal remedies that have shown promise.

frustrated

An animal study published in Phytotherapy research suggests that Xiaoyaosan may help relieve depression by reducing neuroinflammation (inflammation of the brain and spinal cord).

It’s a controversial theory in which imbalances in gut flora, bacteria, and other microbes in the digestive tract are thought to contribute to neuroinflammation, which in turn leads to depression. Xiaoyaosan is said to help by creating compounds that help normalize imbalances.

Published research review Evidence-Based Complementary and Alternative Medicine Twenty-six high-quality trials involving 1,837 people with depression were evaluated. The researchers concluded that taking Xiaoyaosan with antidepressants appeared to improve depression. However, it has no direct effect on depression by itself.

Post Traumatic Stress Disorder (PTSD)

In 2009, researchers found that Xiaoyaosan reduced anxiety behaviors in stressed rats.

A later study, also involving rats, linked this effect to a hormone called a natural hormone. alloprogesterone This is thought to play a role in post-traumatic stress syndrome (PTSD). It was found that taking Xiaoyaosan daily not only reduced anxiety behaviors, but also increased isogesterone levels in the brain.

Anti-inflammatory compounds found in Xiaoyansan, known as Paeoniflorin and Isoliquiritigeninmay also reduce PTSD symptoms, according to a 2017 review Frontiers in PharmacologyThe researchers found that both compounds appeared to alter brain pathways associated with PTSD.

A laboratory-based study published in Scientific Reports Xiaoyaosan was shown to counteract oxidative stress in the brain in a similar manner to the antidepressant drug Prozac (fluoxetine), which is commonly used to treat PTSD. Oxidative stress is damage to cells caused by unstable atoms called free radicals. In the brain, this leads to neuroinflammation and an increased risk of depression.

indigestion

Xiaoyaosan is traditionally used to soothe “stomach acid”, also known as functional indigestion or chronic indigestion.

According to published in Journal of Gastroenterology and HepatologyXiaoyaosan relieves symptoms of indigestion (stomach upset, nausea, bloating, belching) better than acid reflux drugs such as Motilium (domperidone) and Reglan (metoclopramide).

2018 in review Advances in the treatment of gastroenterology The results were confirmed and showed that Xiaoyaosan was more effective in relieving indigestion than either of the two drugs.

Despite the positive findings, high-quality research is lacking in these reviews.

There is some evidence that Xiaoyaosan may help treat depression, indigestion, and post-traumatic stress disorder (PTSD). Even so, evidence remains scant due to the lack of high-quality studies in humans to support its use.

According to the National Center for Complementary and Integrative Health, products imported from China pose additional risks because the ingredients are often written in Chinese and are known to contain heavy metals, drugs and other contaminants.

When choosing supplements, look for products certified by third-party agencies, such as ConsumerLab, United States Pharmacopeia (USP), or NSF International. These certification bodies ensure that supplements are pure and contain only the ingredients listed on the product label.
