Lophatherum (dan zhu ye)

What is lophatherum? What is it used for?

Lophatherum is a type of bamboo native to Asia. Instead of having a rigid, cane-like stem like most bamboos, lophatherum grows as a type of long-leaf grass. The parts of the lophatherum used in herbal formulas are the leaves, which are gathered in the summer, dried in the sun, and cut into pieces.

In traditional Chinese medicine, lophatherum is considered to have sweet, bland and cold properties, and is associated with the Heart, Small Intestine and Stomach meridians. Lophatherum helps to clear heat in the stomach or heart (manifested as irritability, canker cores and swollen gums), remove heat in the small intestine, and promote urination.

How much lophatherum should I take?

The typical dose of lophatherum is between six and nine grams, decocted in water for oral administration.

What forms of lophatherum are available?

Dried, cut lophatherum leaves can be found at many Asian markets and specialty stores. Some shops also sell lophatherum as part of a larger herbal formula.

What can happen if I take too much lophatherum? Are there any interactions I should be aware of? What precautions should I take?

As of this writing, there are no known drug interactions or side-effects associated with taking large doses of lophatherum leaf. However, lophatherum should not be used by women who are pregnant or breastfeeding.

It’s Time to Stop Prescribing Points
It's Time to Stop Prescribing Points

A student stands over a patient, needle poised. They have a “perfect” prescription: a textbook combination of points harvested from a lecture slide on chronic lower back pain. But as the needle meets the skin, the student hesitates - the symptom of a quiet habit that has taken hold of our profession. We routinely say we “prescribe” points. It sounds efficient. It echoes the authority of biomedical culture and fits neatly into the insurance field. But vocabulary is never neutral; repeated long enough, it dictates behavior.

Open the Orifices: Point Combinations for Allergy Presentations
Open the Orifices: Point Combinations for Allergy Presentations

Acupuncture can be highly effective in cases of nasal congestion so common in allergy presentations; so much so that I often treat such issues using acupuncture protocols alone. In cases of seasonal allergies with highly predictable causes such as obvious elevations of environmental allergens, I use a skeleton acupuncture prescription that can easily be fleshed out to target potential underlying patterns and effectively customized to the patient.

Profession at a Crossroads: What Must Change
Profession at a Crossroads: What Must Change

The field of acupuncture in the U.S. continues to grow in visibility, patient demand and clinical effectiveness. Yet behind the curtain, many acupuncturists are quietly struggling to keep their doors open. While the profession is rooted in centuries of healing tradition, modern economic pressures – particularly those driven by insurance limitations, low reimbursement rates and job-market saturation – are making it increasingly difficult for licensed acupuncturists to thrive.
