Objective: To compare the efficiency of extraction of boiling powder and traditional herbal pieces of root and rhizome, flower, leaf and whole plant medicinal materials for providing a reference for the study and clinical application of boiling powder.
Methods: 19 kinds of root and rhizome herbs, the 4 kinds of flower medicinal materials, the 2 kinds of leaf medicinal materials and the 2 kinds of whole plant medicinal materials were chosen as the researh object and were crushed into boiling powder. The contents of the active ingredients and dry extract rate in the water decoction were set as the index to compare the extraction efficiency of boiling powder and traditional herbal pieces.
Results: Boiling powder was added ten times of water, decocted one time, decoction time was only ten min, the dry extract rate and the concentration of ingredients in the decoction of boiling powder were not less than those in the traditional decoction of herbal pieces( ten times of water, decoction time was 50 min),this difference was mainly caused by the different of texture density and size of the medicinal materials.
Conclusion: The boiling powder can not only save time and facilitate the patient, but also save a lot of medicinal materials from the perspective of chemical medicine, which is beneficial to the sustainable development of medicinal material resources.

Continuous microenvironment modulation is an ongoing challenge in wound dressing, which includes excessive exudate absorption, oxygen delivery, bacterial inhibition and angiogenesis. Herein, we developed an construction strategy to fabricate a self-retaining double-layered wound dressing, where the top layer precursor was composed of Ca-containing polyvinyl butyral (PVB) solution dispersed with hydroxypropyl methylcellulose (HPMC) particles, and the bottom one consisted of sodium alginate (Alg) solution blended with Ag-doped mesoporous bioactive glass powders (Ag-MBG). When in use, both precursors were simultaneously squeezed out from the twin nozzles connected to the individual chambers of a twin-chambered syringe, whereby Ca in the top layer rapidly migrated downwards to crosslink Alg in the bottom layer, leading to the formation of an Alg/Ag-MBG (AA) functional hydrogel for filling an irregular wound.

Purpose Of Review: There is an increasing awareness among clinicians that industrial and household food processing methods can increase or decrease the allergenicity of foods. Modification to allergen properties through processing can enable dietary liberations. Reduced allergenicity may also allow for lower risk immunotherapy approaches.

Article Synopsis
- Microplastics are released during the preparation of homemade saline solutions, primarily from the tearing of powder packets and mixing with water, posing risks to humans and the environment.
- The study utilized polypropylene nasal irrigation bottles and compared microplastic content in samples with and without sodium chloride, revealing no significant difference in microplastic levels between the two groups.
- Identified polymers included polypropylene, polyethylene, and polyethylene terephthalate, with control samples containing more fibers, while the powder-added samples had a higher proportion of fragments.

Indigenous fruits and vegetables can improve food security and biodiversity. However, their use is hindered by perishability, seasonal availability, cooking losses, lack of nutritional composition data, and connections to low socioeconomic status. This study aimed to process cowpea leaves into powder and determine the effect of five home-cooking methods on their protein, functional, physicochemical, and heavy metal profiles.

Background: The emergence of multidrug resistant Candida species to available drugs has led to renewed interest in the use of herbal medicines globally. This study scientifically verified antifungal effectiveness of five commonly used plant species in Pader district, against selected pathogenic candida strains.
Methods: Powdered roots of Momordica foetida, Sansevieria dawei and Distimake dissectus; and stem barks of Khaya anthotheca and Mitragyna rubrostipulata were extracted sequentially using petroleum ether and methanol, respectively; and total water extraction at 24.
