If you decide to take it orally, which will likely provide benefits in addition to taking it topically, you would be fine with about 1.5 g per day of the whole herb. You can make a tea from it. I generally take the remaining herb and blend into my smoothie.
Thanks for the feedback.
Here are the notes I had collected on this herb -
Mo Han Lian (Eclipta, Eclipta prostrata)
This herb has a long history of use in hair growth promoting formulas in Ayurvedic and Chinese medicine. (Roy et al. 2008; Chen and Chen 2009; Datta et al. 2009) Eclipta is known...
I've never seen reference to increasing pattern baldness in the literature, but there are reports of temporarily increased shedding during the first weeks of use.
According to the literature, pattern baldness can start as early as 12, and show marked progression by age 17.
If someone is showing signs of hair loss before this age, its probably not traditional pattern baldness.
