So im doing solid phase extraction of a herbal extract. Then, i'm doing total phenolic content using the folin-ciocalteu assay. I.ve done the gallic acid standard with r2=0.98 with straight line eqn= 0.0085x -0.123. but then ive been wondering how do i use the tpc eqn? tpc=c v/m. c i can get from the equation. but for v and m? do i use the loading concentration data where i use 6 mg/ml or i use the concentration finished product of dissolve dried fraction (10 mg/ml). then the question also comes to mind should i use the concentration before putting the folin reagent which is 10 mg/ml or the diluted version (60 ul folin, 60 ul sodium carbonate, 150 ul water and 30 ul of extract which makes it 1 mg/ml)? please im so confused

Answer
My area of expertise in herbology is in Chinese herbs, but generally speaking, in a clinical setting, your choice in herbs for your prescription will depend on the patient's presenting symptoms and the syndrome pattern that you diagnose them with. Most herbal prescriptions (at least the bulk of mine) were short term ones (generally 1 to 2 weeks worth), then a re-evaluation of the patient's condition. With Chinese herbs, there are generally several ways that they are dispensed. Raw, dried herbs (which I did not use simply due to convenience - both mine and the patient's), and powdered, freeze dried ones (which I did). The brand I stuck to (due to dosing and familiarity) was KPC. With this brand, herbs came in both single herb powders, and classical formula powders. Generally, you would choose the classic formula that was closest to the patient's complaints, then modify the prescription with single add-on herbs to get the more exact prescription. Initially in my practice I carried a pharmacy, but later on, I switched to an external dispensary as it was more convenient and cost effective both because I no longer had to worry about spoilage, and because the dispensary would mail the finished prescription to my patient's home.
Technology (ie: EMR) wasn't used up until I retired as it wasn't particularly available, which meant you had to know your herbs well when deciding on your prescription. As you are probably aware, there are many possible solutions as far as prescription goes. Hopefully my answer is helpful to you.

How to prevent saponification of herbal creams? I want to make a vanishing cream by some herbal extracts
Relevant answer
Answer
I have got some information from two books, you can see it in references:
Saponification in herbal creams can lead to unwanted changes in texture, stability, and efficacy. To prevent this, careful selection of ingredients and proper formulation techniques are essential. Below are detailed steps and considerations to prevent saponification and successfully create a vanishing cream with herbal extracts.
Key Steps to Prevent Saponification
  1. Choose the Right Emulsifiers:Use non-soap emulsifiers to stabilize the emulsion. Avoid using alkaline emulsifiers that can react with fatty acids to form soap. Examples include glyceryl stearate, cetyl alcohol, and cetearyl alcohol (Rähse, 2019).
  2. Maintain Optimal pH:Formulate the cream at a slightly acidic pH (4.5-5.5) to prevent alkaline conditions that favor saponification. Use pH buffers like citric acid/citrate systems to stabilize the pH (Rähse, 2019).
  3. Incorporate Antioxidants:Add antioxidants to prevent the oxidation of oils, which can lead to the formation of free fatty acids that might react with alkali. Common antioxidants include tocopherol (vitamin E), ascorbyl palmitate (vitamin C), and alpha-lipoic acid (Rähse, 2019).
  4. Select Stable Oils and Butters:Use oils and butters that are less prone to oxidation and rancidity, such as jojoba oil, shea butter, and fractionated coconut oil. Avoid oils with high levels of unsaturated fats that can easily oxidize (Rähse, 2019).
  5. Use Airless Packaging:Store the cream in airless dispensers to minimize contact with air, reducing the risk of oxidation and microbial growth (Rähse, 2019).
Formulating Vanishing Cream with Herbal Extracts
  1. Base Ingredients: Water Phase:Distilled water or herbal infusions (e.g., chamomile or green tea). Humectants like glycerin or propylene glycol to retain moisture. Oil Phase:Emollients like cetyl alcohol, stearic acid. Stable oils like jojoba oil or shea butter. Emulsifiers such as glyceryl stearate or cetearyl alcohol.
  2. Active Herbal Extracts:Aloe vera extract for its soothing and moisturizing properties. Green tea extract for its antioxidant benefits. Calendula extract for anti-inflammatory effects.
  3. Procedure: Phase A (Water Phase):Combine water, glycerin, and any water-soluble extracts. Heat to 70-75°C. Phase B (Oil Phase):Combine oils, butters, and emulsifiers. Heat to 70-75°C until fully melted. Emulsification:Slowly add Phase B to Phase A while continuously stirring. Homogenize the mixture until a stable emulsion forms. Cool Down Phase:Allow the mixture to cool to below 40°C. Add heat-sensitive ingredients like essential oils, preservatives, and any additional extracts. Adjust the pH to 5-5.5 if necessary.
  4. Preservatives and Final Adjustments:Use preservatives suitable for natural products, such as phenoxyethanol or potassium sorbate, to prevent microbial growth (Rähse, 2019). Ensure the final product has a smooth texture and a pleasant feel on the skin.
Conclusion
By carefully selecting ingredients and maintaining optimal formulation conditions, you can prevent saponification in herbal creams and create a stable, effective vanishing cream. The use of non-soap emulsifiers, pH buffers, antioxidants, and airless packaging are critical in achieving this goal.

We conducted SRB assay to survey the cytotoxicity of a herbal extract with the concentration from 0.5 to 18 mg/mL. However, the inhibition percent dramatically decrease at 15 mg/mL and 18 mg/mL while it still increased at concentrations being from 0.5 to 12 mg/mL. What can lead to this phenomenon?
Relevant answer
Answer
Hi,
The phenomenon of decreased cytotoxicity at higher concentrations of herbal extracts, as observed through the Sulforhodamine B (SRB) assay, presents a paradox within the realm of pharmacology and toxicology. This observation suggests a complex interplay between the biological activity of phytochemicals and the physiological mechanisms of the cells exposed to them. To understand this phenomenon, it is necessary to integrate knowledge from various scientific disciplines, such as pharmacology, chemistry, and cell biology.
The increase in cytotoxic effects with increasing concentrations of a herbal extract can be explained by the effective interaction of the extract's active components with their target receptors or enzymes within the cell. This interaction usually follows a dose-dependent manner until a certain point. However, the decrease in cytotoxicity at higher concentrations suggests that saturation has occurred. Once the targets are fully engaged, additional molecules of the extract cannot further enhance the biological response, leading to a plateau or even a decrease in the observed effect.
Beyond receptor saturation, cells have evolved various mechanisms to protect against excessive damage from xenobiotics, including herbal extracts. These mechanisms involve upregulation of detoxification pathways, such as those involving cytochrome P450 enzymes, and activation of efflux pumps that remove toxic substances from the cell's interior. At higher concentrations of the herbal extract, protective mechanisms may be activated more robustly, reducing the cytotoxic impact of the extract by lowering the intracellular concentration of active compounds.
Another important consideration is the stability of the phytochemicals in the extract. At higher concentrations, some compounds may become unstable, aggregate, or undergo chemical modifications that reduce their bioactivity. This instability can be influenced by assay conditions, such as changes in pH, solvent interactions, or the ionic strength of the medium, which could potentially lead to misleading interpretations of cytotoxicity.
It is important to consider the impact of high concentrations of herbal extracts on cell density and nutrient availability within the assay system. This can cause added stress from nutrient depletion and altered metabolic states, leading to non-specific effects that may reduce the apparent cytotoxicity and complicate the interpretation of results.
Furthermore, the high concentrations can lead to non-specific binding of extract components to proteins and other macromolecules in the assay medium, or even to precipitation of some compounds. These phenomena can significantly reduce the bioavailable concentration of active phytochemicals, thereby diminishing the observed cytotoxic effect.

Why did you expect anything of n herbal preparations and why call it any "drug"?
Zone of inhibition is fairly meaningless by itself but lack of efficacy in this context probably means it won't function as an effective antimicrobial drug. If these are offered in that context - they're BS.

I am conducting a study to assess the quality of selected parts of some herbal materials and also develop acceptance criteria for their quality attributes. I am supposed to sample these materials from across the length and breadth of the country and I am hoping to stratify the country into strata and further divide each stratum into clusters, and then randomly sample the materials from each of the clusters picked up through systematic sampling.
My challenge is with the calculation of a 'realistic' sample size that can then be used to determine the number of clusters and the number of samples from each cluster. Very often what I see in literature tends to be convenient sampling, which may not be representative of the population. The focus of my study however requires that my sampling is representative of the population in the country (and also realistic), especially because of the part that has to do with setting acceptance criteria.
I would be very grateful for your technical assistance. Thank you.
Relevant answer
Answer
Hi Emmanuel,
A country is too large for this type of survey. I guess you need to use multi-stage sampling also known as cluster sampling.
You will need to stratify the country into separate homogenous units (e.g. based on ecology, ethnicity, administrative units, etc.). Within each cluster again find a homogenous distinguishing feature. Go on identifying subunits until the smallest possible one and then randomly selected units within the last unit. A very useful text on this sampling approach is by De Vaus (2014). De Vaus, D. 2014. Surveys In Social Research. 6th edition. Routledge.
What I have not yet figured out is if I have e.g. 10 units at the second stage (cluster), what proportion I should take of these 10.

Solid herbal material or food material when manufactured, their composition already analyzed including its metals content , so there are no toxic metals exist to the composition of Solid herbal material or food material.
Normally, heavy metals removal processes are bio accumulation and bio-absorption, by plants .

Other literature reports regarding bio accumulation and bio-absorption of heavy metals other plants.

Ex: DMSO, PEG400, ....

Relevant answer
Answer
sesame oil would not be toxic per se, but there would be a limit beyond which digestive difficulties would be encountered which would threaten the reproducibility of your experiment.Perhaps if you did not take the extract to complete dryness on the rotavap, you could more easily mix it into a vehicle that the mice could tolerate- When you find a suitable vehicle, try the blank vehicle on the mice and record observations.

Is it justifiable to use a negative control when previous studies have proven that adjunctive use of Chlorhexidine is better than only SRP or placebo. When we know that adjunctive use of a gold standard is available that will give additional benefit to the patient, is it ethical to include only SRP or placebo group?
