Traditional Chinese Medicine (TCM) and Allergic Diseases.

Purpose Of Review: This paper purports to review recent relevant publications on the efficacy of traditional Chinese medicine in treating allergic diseases, to illustrate the pertinent mechanisms of action of TCM, and to explore the possible role of TCM in the management of allergic diseases in the foreseeable future. As TCM embodies multiple treatment modalities, only the most popular two, namely CHM (Chinese herbal medicine) and acupuncture, were discussed. Publications, especially reviews involving randomized controlled trials (RCTs) on the use of TCM on allergic diseases, published up to June 2019 were reviewed and analyzed.

MAP30 protein from Momordica charantia is therapeutic and has synergic activity with cisplatin against ovarian cancer in vivo by altering metabolism and inducing ferroptosis.

Increasing evidence shows that Traditional Chinese Medicine (TCM) has an obvious appeal for cancer treatment, but there is still a lack of scientific investigation of its underlying molecular mechanisms. Bitter melon or bitter gourd (Momordica charantia) is an edible fruit that is commonly consumed, and it is used to cure different diseases in various ancient folk medical practices. We report that a bioactive protein, MAP30, isolated from bitter melon seeds exhibited potent anticancer and anti-chemoresistant effects on ovarian cancer cells.

Intestinal absorption and bioavailability of traditional Chinese medicines: a review of recent experimental progress and implication for quality control.

Objectives: Experimental studies on the pharmacokinetics of traditional Chinese medicines (TCMs) have achieved great progress in recent years. This review aims to summarize the progress made on intestinal absorption and bioavailability of TCMs, and proposes the application of intestinal absorption assays as new tools for the quality and safety control of these medicines.

Key Findings: Since only the absorbed constituents may produce possible therapeutic effect (except those that directly target the digestive tract), intestinal absorption is of utmost importance for the drug action of TCMs, which are usually taken orally.
